Product performance of Si powder
High purity, the scattered performance is good, particle size small, distributed even, is bigger than, the high surface activity the surface area, the pine installs the density to be low, activeness good and so on characteristics. A nanometer silicon may with the graphite either a carbon nanometer tube, or nanometer titanium nitrides and so on compound, makes lithium battery's cathode material, may enhance lithium battery's capacity and the service life. Is the new generation electro-optic semiconducting material, has the wide gap energy.


Application direction of Si powder
1). Uses a nanometer silica flour to make the nanometer silicon line to use in the charge lithium battery cathode material, or with makes the charge lithium battery cathode material in the nanometer silica flour surface gable graphite, enhanced the charge lithium battery 3 time of above electric capacities and the charging and discharging cycle-indices;
2). Nanometers silica flour use in the thermostable coating and the fire-proof material;
3). Nanometers silicon may apply in the coating, forms a silicon nanometer thin film, is applied above massively the solar energy;
4). Nanometers silica flour and the diamond high pressure mix form the silicon carbide---The diamond compound materials, with make the cutting tool.

Storage conditions of Si powder
This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.
