  • Spherical  Zinc Oxide ZNO Nanostructures Application
    Spherical Zinc Oxide ZNO Nanostructures Application
    Spherical  Zinc Oxide ZNO Nanostructures Application     Compared with ordinary zinc oxide, Zinc Oxide ZNO Nanostructures has many other excellent performance. At present the main application areas are rubber products, high-grade paint, ink and paint, sunscreen and anti-ultraviolet fabric, sewage treatment,etc.   1. Zinc Oxide ZNO Nanostructures in Rubber Industry   ZnO nanopowder is the most effective inorganic active agent and vulcanization accelerator in rubber industry.  Zinc Oxide ZNO Nanostructures with small particle size 20-30nm, larege specific surface area, good dispersion, loose, porous, good liquidity and good affinity with rubber, easily dispersed whilc melting, low heat plastic material, breaking small deformation , good elasticity, can improve the material process performance and physical properties, thus it's used in the manufacture of high-speed wear-resistant rubber products, such as aircraft tires, high-class passenger car radial tire, with performance of anti-aging, anti-friction fire, long life, and greatly improves finish, mechanical strength, temperature and aging resistance of rubber products,especially wear resistance.  In addition, Zinc Oxide nano as a vulcanization system in the rubber system, whose additive is high.The large specific gravity and  filling amount of ordinary ZnO, whose influence on its material density, product life and energy consumption is detrimental. However, the use of Nano grade Zinc Oxide, the amountis only 30% -50% compared to the ordinary one,which reduces the cost of production, and the performance in the tensile properties, heat, aging, etc are far superior to ordinary zinc oxide powder.   2. Zinc Oxide ZNO Nanostructures in Ceramic industry   Because of very small particle size, large specific surface area and high chemical properties,nano ZnO can significantly lower the sintering densification of materials, save energy, make the ceramic material composition densification, homogenization, improve the performance of ceramic materials, the reliability of its use. Controling the composition and structure of materials on the structural level of nano materials is conducive to give full potential performance of ceramic materials. In addition, because the particle size of ceramic material determines the microstructure and macroscopic properties of ceramic materials, if the particles of the powders are uniformly packed and the sintering shrinkage is uniform and the grain grows uniformly, then the smaller the particle size, the smaller the resulting defects, and the higher the strength of the prepared material, which may result in some unique performance that large particles do not have.   3. Nano Zinc Oxide in Other Areas With the deepening understanding of the performance of nano Zinc Oxide, its applications continue to expand, for example, in the traditional coating technology, adding nano ZnO can further improve the protective capacity, making resistance to atmospheric damage and anti-degradation, color,etc.With a certain percentage of Zinc Oxide nanopowder added to the propionic acid coating, it can be made into excellent nano antibacterial coating. Making use of the sensitive properties of nano ZnO, can produce a high sensitivity gas alarm and hygrometer.           As a new type of semiconductor materials, Zinc Oxide ZNO Nanostructures has become a new type of high-performance fine inorganic products in the 21st century. At present, researchers at home and abroad have developed a variety of methods to prepare various forms of nano zinc oxide products and achieve a lot. However, there are still some shortcomings such as high cost, complicated process and difficulty of industrialization in the preparation method. In addition, the research on the structure and application performance of nano ZnO is not deep, so the follow-up research will focus on the development of simple, high-efficient and easy industrial production methods. With the further study of the material structure on its optical, electrical, magnetic and acoustic properties, it is expected that with the continuous improvement of the preparation method of nano zinc oxide, the nano-size effect of nano-sized oxides, and the study will have a full-speed development stage. by Jemma
  • Silicon Carbide nano particle
    Silicon Carbide nano particle dosage influencing on composite friction performance
    Silicon Carbide nano particle dosage influencing on composite friction performance       For Silicon carbide nano particle is with Moh’s hardness about 9.2 which is a hard material. With its hardness, SiC nano powder is suitable to be additive for composite material and improve their toughened and strengthened.        For SiC nano additive has different influence to the relative density, hardness, electrical conductivity and friction and wear properties of the composites. Generally the relative density of the composites decreased with the increase of the content of nano SiC particles. The hardness of the composites increased with the increase of the content of SiC nano particles, but when the nano  SiC particles agglomerated, the hardness increased . However the content of silicon carbide nano powder affect to the conductivity of material is opposite. When the content of  SiC nano particle increase the conductivity of the composite decreases. According to some study when the content of SiC particles is about 0.5% -3%, the wear rate of the composites decreases with the increase of SiC content. When the SiC content is more than 3%, the wear rate of the composites increased with the increase of the content of  SiC nano-particles. The abrasive wear and the friction coefficient decreased with the increase of the SiC content. We provide our customers:   High quality silicon carbide particles(50nm,100nm,500nm,1um,5um,7um,10um,15um)   Volume pricing   Reliable service   Technical assistance Our products are all available with small quantity for researchers and bulk order for industry groups.  If you have any questions, please feel free to contact us. thank you. by Lyla

        We, Hongwu Nanometer, are offering different shape & size metal oxide Nanoparticles and Nanopowders including high quality NIO Nickel oxide nanoparticles. Stock#: S672, particle size 20-30nm, 99.6%. 1. Nickel Oxide Catalyst     NiO is a kind of oxidation catalyst with good catalytic effect. Ni2 + has 3d orbit, which has the tendency of preferentially adsorbing polyelectron, and also activates other reducing gases and catalyzes the oxygen. During the decomposition, synthesis and the conversion process of the organic matters,such as gasoline hydrocracking, a petrochemical treatment of hydrocarbon conversion. In the process of heavy oil hydrogenation, NiO nanoparticle is a good catalyst. In the catalytic combustion of natural gas,using NiO / CuO-ZrO2 composite catalyst to improve its high temperature stability in order to avoid oxidation of N2 in the air to produce NOx and unburned CO under the high temperature of reachtion.  The NiO / Si02 composite catalyst is used in the preparation of carbon nanotubes(CNTs). When the content of Ni is high, the yield of carbon nanotubes is high and the diameter distribution is narrow. However, the content and shape of NiO directly affects the yield and traits of carbon nanotubes. In wastewater treatment, NiO is a catalyst to remove CH4, cyanide and N2 and decompose NOx. As photocatalytic degradation of acid red catalyst, NiO in the treatment of organic dye wastewater and the result is very obvious. 2. Ceramic additives and colouring agent of glass     Nano NiO powder is used to improve the impact strength of ceramic products. When adding NiO (O.02 (wt)%), the electrical properties such as piezoelectric properties and dielectric properties can be improved greatly. The addition of NiO nanoparticle to the glass mainly controls the color of the glass, and a small amount of NiO is contained in the transparent brown transparent glass which can absorb ultraviolet rays. Transparent glass mirrors and decorative glass are added the moderate amount of NiO nanopowder as a coloring agent. 3. Battery electrode material     With the continuous development of communication and information technology, the capacitor has also achieved unprecedented development. Nowadays, supercapacitors have become a research hotspot because they have much higher energy densities and much higher power densities than traditional ones. Research showed that ruthenium oxide is currently the most studied and the best performance of the electrochemical capacitor electrode material. However, its very high price hindered its large-scale applications. And the large internal resistance of activated carbon makes people look to the transition metal oxides. With quasi-capacitive phenomena, transition metal oxides become the super capacitor electrode materials. At present, the use of Ni, Mn, Co and other oxides with the small internal resistance, low cost and large capacity and other characteristics for battery electrode material attracted concerns a lot.As cathode of carbonate molten salt fuel cell, nano NiO, with gas or natural gas as fuel, produced clean energy with higher power generation efficiency than the traditional thermal power generation. Moreover, compared with the ordinary NiO battery, the nano NiO battery owns obvious discharge advantages,  the is obviously increasing discharge capacity, and the greatly improved electrochemical performance of the electrode. 4. Sensor material     NiO nanopartilce has received more and more attention recent years as gas sensor materials. At present, nano NiO has been made into the formaldehyde sensor, CO sensor, H2 sensors used in the actual production. In short, with the rapid development of science and technology, more and more properties of Nickel Oxide nanoparticle woud be dig out and applied in wider fileds.
