Uses of Si Metal Powder

Uses of metal silicon powder: Silicon chemical vapor deposition: Under the action of external energy such as heat, microwaves, lasers and plasma, silane decomposes into silicon and hydrogen under highly diluted hydrogen conditions, and quickly condenses in a gas phase environment to prepare nano-silicon pink.
Ball milling method: Metal silicon powder uses the huge friction generated by mechanical rotation and the interaction between particles to grind larger silicon materials into nano-scale powders. The metal silicon powder produced by ball milling has a high impurity content, the particle size distribution cannot be well managed and controlled, and the post-processing technology is complex.
The main function of metal silicon in magnesia carbon bricks is to consume oxygen in the decarburized layer and increase the oxidation resistance of carbon-containing refractory materials. In carbon-containing refractory materials, metal silicon and aluminum are mainly used for oxidation resistance and reducing carbon oxidation. For the effects of these two antioxidant additives, metal aluminum powder is stronger than metal silicon powder. Some companies believe that metal silicon powder is suitable for refractory materials with lower smelting temperatures. Metal aluminum is suitable for refractory materials with higher operating conditions. Another point is that the high-temperature strength of carbon-containing refractory materials with added metal aluminum is higher than that of carbon-containing refractory materials with added metal silicon.
