silicon metal uses

Silicon metal i s an important raw material for metallurgical cast iron industry. Today, I would like to introduce silicon metal:

Metal silicon is also known as crystalline silicon or industrial silicon, its main use is as an additive in non-iron based alloys. Silicon metal is made of quartz and coke smelted in an electric furnace products, the main component of silicon element content in about 98% (in recent years, containing Si content of 99.99% is also included in the silicon metal), the other impurities for iron, aluminum, calcium and so on. The classification of silicon metal is usually based on the content of iron, aluminum and calcium, the three main impurities contained in the composition of silicon metal. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades. The silicon metal also has some additional products including silicon powder, edge silicon, black silicon, silicon slag and so on. Silicon powder, also known as silicon powder, silicon powder or silica fume, it is widely used in refractory materials and concrete industry.

Silicon metal in the metallurgical casting industry has a very important role, the main uses of silicon metal have the following several aspects:

Silicon metal is used in the production of organosilicon, high purity semiconductor materials and the preparation of alloys for special purposes.

(1) the production of silicone rubber, silicone resin, silicone oil and other silicone.

(2) Manufacturing high purity semiconductors.

(3) alloy preparation.

The silicon metal produced by Henan Stellar Metallurgy Group has stable quality and complete specifications. We are looking forward to cooperating with you.
