Silicon metal knowledge


 This year is the Chinese Year of the Ox. I wish you all good luck in the Year of the Ox.My company Spring Festival holiday is over now, all departments began to work normally, today to share silicon metal little knowledge to you.

Silicon metal also known as crystalline silicon or industrial silicon, its main use is as an additive for non-iron based alloy silicon metal composition is mainly silicon, so and silicon has similar properties.The properties of silicon metal and germanium, lead, tin similar, with semiconductor properties.

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 common uses of silicon metal are:

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

(2) Manufacturing high purity semiconductors.

(3) alloy preparation.

At the beginning of the New Year, the company has launched a huge preferential activities, ferrosilica, silicon metal, silicon slag, electrolytic manganese, graphite powder and other metallurgical resistant materials are large and preferential, welcome to buy!For more information, please contact us at
