Tin Oxide Nanoparticles for Conductive SnO2 ceramic       Ceramic is a good insulator and not conductive material in general. Ceramic is made from oxides mainly; the outer electrons of the atom usually is attracted to the nucleus and are bounded to the surrounding atoms of the atom, then the electrons are not free to move. That makes the general oxide ceramic not conductive. However, by using the Tin oxide nano powder as the main component and mix with Sb2O3, CuO, ZnO, PbO, Fe2O3 and other components to make the ceramic electrode material.     For SnO2 is the main component, adding Sb2O3, CuO, ZnO, PbO, Fe2O3 and other components of the electromagnetic flowmeter with ceramic electrode materials. The conductive ceramic is available to make in ordinary ceramic technology such as in the oxidizing atmosphere at 1300 ~ 1360 ℃ under firing. For the SnO2 conductive ceramic resist the erosion of various concentrations of strong acid, and with excellent conductivity in room temperature. If use of the SnO2 ceramic instead of the current platinum electrode, users could save a lot of platinum and greatly reduce costs. For the SnO2 ceramic is available to use as solar cell electrodes, and the general heating, corrosion-resistant heating and so on.     HW NANO SNO2 TIN OXIDE NANOPARTICLES, PARTICLE SIZE 20NM, 50NM, 80NM...PURITY 99.99%     Tin oxide nanoparticles has application in electronic devices. It is used in liquid crystal displays, optoelectronic devices, solar cells, gas sensors, and resistors. It is also used in anti-static coatings, and energy conserving coatings. It has applications in catalysis. It is used in transparent heating elements. By Lyla

Nano-zinc oxide is a high-end fine inorganic product that exhibits many special properties such as non-migratory, fluorescence, piezoelectricity and UV scatter. Using its wonderful properties in light, electricity, magnetism, and sensitivity, it can manufacture gas sensors, phosphors, varistors, UV shielding materials, image recording materials, piezoelectric materials, varistors, high-efficiency catalysts, magnetic materials, and plastic films. . It has been proved by practice that nano zinc oxide is widely used in various fields such as rubber with its excellent properties.

Good prevented bask raw material is TiO2 nanopowders titanium dioxide white.

Silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity, and impact resistance. At the same time, it has the advantages of high thermal conductivity, oxidation resistance, and good thermal stability. It is often used in packaging materials in the microelectronics industry.

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.
