High Density Metallurgical Silicon Oxidation Resistance Uesd In Smelting Works
Silicon is one of the semi-metals. The melting point is 1420 ° C and the density is 2.34 grams per cubic centimeter. Hard and brittle. It is insoluble in acid at room temperature and easily soluble in alkali. The properties of metallic silicon are similar to those of germanium, lead and tin, and have semiconducting properties. Silicon is extremely rich in resources in the earth's crust, second only to oxygen, accounting for more than a quarter of the total weight of the earth's crust, in the form of silica or silicate. The purest silicon mineral is quartz or silica. Silicon has two allotropes: one is a dark brown amorphous powder, which is active in nature and burns in air; the other is a stable crystal (crystalline silicon). General silica and quartz for glass and other building materials, high quality quartz for alloys, metals and single crystals
1. A large amount of silicon is used for smelting into ferrosilicon alloys as alloying elements in the steel industry, and as a reducing agent in many metal smelting. Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon. Silicon is the raw material of ultra-pure silicon in the electronics industry. The ultra-pure semiconductor monocrystalline silicon electronic device has the advantages of small size, light weight, good reliability and long life.
2. High-power transistors, rectifiers, and solar cells made of silicon single crystal doped with specific trace impurities are better than those made of germanium single crystal. The research on amorphous silicon solar cells is progressing rapidly, and the conversion rate has reached more than 8%. Silicon molybdenum rod electric heating elements can be used up to 1700 ° C, with resistance to aging and good oxidation resistance. Using trichlorosilane produced from silicon, hundreds of silicone lubricants and water-repellent compounds can be formulated.
3. In addition, silicon carbide can be used as an abrasive. The quartz tube made of high-purity silica is an important material for high-purity metal smelting and lighting fixtures. Paper in the 1980s - Silicon People called silicon "paper in the 1980s." This is because paper can only record information, and silicon not only records information, but also processes the information to obtain new information.
