Products Description
Silicon Metal is also known as crystalline silicon or industrial silicon, the production of high-purity semiconductor materials and metal silicon grade to achieve99. 999 (5N) purity, is the industrial purification of elemental silicon, mainly used in the production of organic silicon used in the 3C industry, the preparation of high-purity semiconductor materials can also be used in the preparation of special purposes of the alloy and other aspects of the main used as a non-iron base alloy additive. Silicon is a non-metallic element, blue gray, metallic color, hard and brittle.
The content of silicon accounts for about 26% of the mass of the Earth's crust, with an atomic weight of 28.80 and a density of 2.33g/m3. The melting point is 1410℃ and the boiling point is 2355℃. The classification of the most commonly used grade of metallic silicon is usually classified by the content of the three main impurities of iron, aluminum and calcium contained in the metal silicon composition. 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.
