Product name: Zirconium oxide nanoparticles  Formula: ZrO2  Size: 60-80nm,300-500nm,1-2um  Purity: 99.9%  Shape: monoclinic  Color: white  CAS : 1314-23-4  Molecular: 123.22  Melting point: ~2700℃  Boiling point: ~4300℃  Water solubility: not soluble Zro2 nanoparticles properties: 1.Odourless tasteless white crystals, soluble in water, hydrochloric acid and dilute sulphuric acid. 2.Chemical inertness and high melting point, high resistivity, high refractive index and the properties of low thermal expansion coefficient. Zirconium oxide ZrO2 nanoparticles application: 1. Refractory material . Zirconia fiber is a kind of polycrystalline mass refractory fiber material. Due to the high melting point, no oxidation ZrO2 material itself and other excellent high temperature properties, ZrO2 fiber is better than the alumina fiber, mullite fiber, aluminum silicate fiber, and other varieties of refractory fiber the use of higher temperature.Are a top refractory fiber material in the  international. 2. Ceramic material. Because the refractive index of a zirconium oxide, high melting point, corrosion resistance is strong, so used for ceramics raw material. Piezoelectric ceramic filter, speaker ultrasonic acoustic detector, etc. Ceramics for daily use (industrial ceramic glaze), precious metal smelting with zirconium tube and zirconium brick. Nano-sized zirconium oxide can also be used as a polishing agent, abrasive, piezoelectric ceramics, precision ceramics, ceramic glaze and high temperature pigment matrix material. 3. Gas turbine. Plasma spraying cubic zirconia thermal barrier coating application in aerospace and industrial gas turbine has great progress, within limits has been used in gas turbine turbine parts.Can significantly improve the durability of the high temperature parts, or allow to improve gas temperature or reduce cooling gas to the dosage and high temperature parts of constant temperature that can improve the efficiency of the engine.   For the further information of zro2 nanoparticles, please contact us freely.

     HW NANO Bismuth oxide powder, 20-30nm,99.5%, yellow solid powder      Nanometer bismuth oxide powder is an important functional material, and is widely used as excellent organic synthesis catalyst, ceramic coloring agents, flame retardant plastics, pharmaceutical astringents, glass additives, high refractive index glass and glass manufacturing nuclear engineering and nuclear reactor fuel, and also is an important dopant in the electronics industry.        Nanometer bismuth oxide with the properties of the general size and due to the finer granularity, Bi2O3 nano particle can be used to inorganic pigments, optical materials, electronic materials superconducting materials, special functional ceramic material, a cathode ray tube wall paint and so on.       Also the Bi-based composite oxide is a good photocatalyst which uses solar energy to eliminate pollutants. To protect the environment, maintain ecological balance, to achieve sustainable development contributes a lot. Bi-based composite oxide due to its unique physical properties can be used as an ion conductor, sound and light materials, light conductors, gas sensors, and photocatalysts. by lyla

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.
