Silicon metal, also known as crystalline silicon or industrial silicon, is a product smelted from quartz and coke in an electric furnace. Its main component is silicon, which accounts for about 98%. Other impurities include iron, aluminum, calcium, etc.
Physical and chemical properties: Silicon metal is a semi-metal with a melting point of 1420°C and a density of 2.34 g/cm3. It is insoluble in acid at room temperature, but easily soluble in alkali. It has semiconductor properties, similar to germanium, lead, and tin.
Main grades: Downstream customers are aluminum plants that produce silica gel.
The main grades of metallic silicon are silicon 97, 853, 553, 441, 331, 3303, 2202, and 1101.
