  Silicon Metal Smelting Anyang Hengsheng

  In the metallurgical theory of metal silicon, a major theoretical breakthrough was the discovery of a new lowvalence oxide of silicon—SiO. This was confirmed by recovering a large amount of SiO2 dust from a silicon metal duster. It can be further confirmed that oxide SiO plays a very important role in the smelting, and it is an essential intermediate product. The formation of SiO in the Si
