What are the production processes of metal silicon powder?
What are the production processes of metal silicon powder?
Metal silicon is a common metallurgical raw material with good high temperature resistance and good performance in the manufacture of semiconductor components. Metal silicon powder is a powdered material processed from metal silicon, and the quality of metal silicon powder obtained by different production processes is also different. In addition to metal silicon powder, there will be some other products in the production of metal silicon powder. Which method to use depends on the actual situation. So what are the production processes of metal silicon powder?
The preparation method of metal silicon powder is relatively simple and easy, and the preparation principle is also very simple and easy to understand. After a certain amount of coarse silicon powder is dispersed, it is sent into the plasma arc with inert gas and instantly heated, so that the coarse silicon powder is instantly evaporated into silicon vapor at a higher temperature, and then the silicon vapor enters the cooling area and condenses into nano-scale metal silicon powder.
