The sensor is one of the most promising fields for application of nano-metal particles. The characteristics of nano metal powders such as large surface area, high special activity and extra tidy is consistent with multi-functional, miniaturization and high-speed required by the sensors. In addition, as the sensor material, it also requires broad functions, high sensitivity, characteristics of fast response, wide detection range, good selectivity, high resistance, stable and reliable. Nano metal powder can better meet the above requirements.
In the chemical industry, nano-metal powder used catalysts, nano-materials to show their talents on the one hand. Such as ultra-fine boron powder and chromic acid ammonium powder can be used as explosives effective catalyst. Ultra fine platinum powder and tungsten carbide powder is efficient hydrogenation catalysts. Fine silver powder can be used as a catalyst for ethylene oxide; ultrafine nickel powder, silver powder light sintered body as chemical batteries, fuel cells and photochemical cell electrodes can increase the contact area between the liquid or gas. It also increases cell efficiency and becomes miniaturization.
Light sintering of the ultrafine metal powder porous filters can be generated as the adsorption of hydrogen
