HW nano material sale high purity bi2o3 nano bismuth oxide for electronic ceramics and piezoresistor use O765: Nano bismuth oxide, particle size 20-30nm,99.5% O766: Nano bismuth oxide, particle size 30-50nm,99.5%       Bi2O3 nano bismuth oxide is an important functional material. The use of bismuth oxide is not only a good catalyst for organic synthesis, ceramic coloring agents, plastic flame retardants, pharmaceutical astringents, glass additives, high refractive glass and nuclear engineering glass manufacturing and nuclear reactor fuel, but also is a kind of important doping powder material in the electronics industry.       Bi2O3 nano bismuth oxide powder is mainly used in the chemical industry (such as chemical reagents, bismuth salt manufacturing, etc.), the glass industry (mainly used for coloring), the electronics industry (electronic ceramics, etc.) and other industries (such as fire paper manufacturing, nuclear reactor fuel. Among them, the electronics industry is the most widely used bismuth oxide industry, mainly used in varistors, thermistors, zinc oxide arrester and CRT, and other fields. If the material from the points, bismuth oxide is mainly used for electronic ceramic powder materials, electrolyte materials, optoelectronic materials, high-temperature superconducting materials, catalysts. Electronic ceramic powder materials the field of electronic ceramics are a mature and dynamic field for the application of bismuth oxide.        Bismuth oxide as an important additive in the electronic ceramic powder material, the purity of the general requirements of more than 99.5%. The main application targets are three categories that are zinc oxide varistor, ceramic capacitors, and ferrite magnetic materials. In the development of electronic ceramics, the United States is one of the top one in the world. While Japan relies on mass production and advanced technology to occupy the world's ceramic market share of 60%. With the nano bismuth oxide research and development and homogenization of manufacturing technology innovation will also greatly promote the electronic ceramic-related components to improve performance and reduce production costs. Bismuth oxide in zinc oxide varistor mainly plays a role in the formation of agents, zinc oxide varistor with high nonlinear voltammetry, the characteristics of the main contributors.

Nanometer sized copper powders CU for preparation immune enhancement drug use.

      Titanium dioxide material can selectively etch metal nanoparticles through electron transfer with metal Ag nanoparticles in the excited state, and change the optical absorption characteristics of the material, thus the Ag/Tio2 nanomaterials can change color under the light excitation of different wavelengths.       Experimental demonstration: 1) 500 ℃ heat treatment was carried out on the TIO2 thin film，it is helpful for photocatalytic deposition of Ag particles, and Ag/TIO2 thin film has the obvious photochromic phenomenon; 2) as the content increase of Ag particles deposited on TIO2 films, the photochromic rate of Ag/TIO2 films increases correspondingly, but the reaction rate of photochromic reaction is inhibited when the content of Ag particles exceeds a certain amount.       If you're interested in the material, please not hesitate to contact us , and we will make a tailor for matching your products.

Magnesium Oxide nano particles antibacterial 30-50nm         Magnesium Oxide nano particle(MGO) with a wide band-gap is an important inorganic material. MgO nano powder is a promising antibacterial agent because of its high resistance to harsh environment.  For the antibacterial ablity of MgO nano powder is related to the particle size. The antibacterial activity was increased with the decrease of the particle size of MgO nano. For particles in the size range 50-70 nm, the bactericidal efficacy of nano-MgO increased slowly with decreasing particle size. When the size under 40 nm, the bactericidal efficacy of MgO nano increases a lot and could kill more bacteria. This proves that the particle size is smaller the antibacterial efficacy of MgO is stronger. MgO nano particles penetrated the bacterial cell wall and cell membrane. For the size is smaller, and then killed more bacteria. Also MgO nano particles with large specific surface area increase as the size of the nano particles decreases. For the large surface area with lots of reactive groups on the particle surface and high antibacterial activity will be obvious.       Hongwu International Group Ltd is committed to provide high-quality Magnesium Oxide nano particles(30-50nm, 99.9%) with the most reasonable price for customers who are doing nanotech research and have formed a complete cycle of researching, manufacturing, marketing and after-sale servicing. Our products have been sold to many countries around the world.

Nano Silver-tin alloy(Hongwu nanomaterial is supplying it) is a binary alloy of silver and tin, which is a kind of low temperature solder. It is suitable for brazing copper alloy and other parts which are limited in temperature and require high strength.
