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

High filling & low viscosity flake silver powders for epoxy resin conductive adhesive use       Conductive adhesive is a special kind of adhesion agent, mainly composed of resin and conductive fillers, such as silver powder, gold powder, copper powder, nickel powder, graphite powders, etc.), can be used as adhesive materials in microelectronics components, encapsulation manufacturing process.         Conductive adhesive with flake silver powder has excellent electrical conductivity, adhesion and chemical stability. Silver powder almost not be oxidized in the rubber, in air its oxidation speed is very slow, even if is oxidized, silver oxide generated still has good electrical conductivity. therefore, in the market, especially on the high reliability requirements of electric installation, flake silver powders as conductive filler is used mostly. And in the choice of matrix resin, epoxy resin is the best because of its high content of active group, high cohesive strength, good adhesion and excellent mechanical properties.       HW NANO flake silver powder, with particle size <1um, 1-3um,5-8um,10um, purity 99.99%. Specific surface area and apparent/bulk density are adjustable flexibly. It is available with small quantity for researchers and bulk order for industry groups.          Silver powder filling quantity influence on the properties of conductive silver glue. after silver powders as conductive filler is added to the epoxy adhesive, the conductive mechanism is the contact between of silver powders.After system curing, silver powders connect into chain circuit with each other, presents the conductivity. the data shows that the adding quantity of silver powder to 80% or so, the conductivity is the best.  

Copper zinc alloy nanoparticles factory direct offer, are widely used in lubricating additives and catalyst.

For  the nano nickel, we could not only supply in powder form, but also could supply in dispersion form, welcome to inquiry.
