Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys.
Metallic silicon is a product made of quartz and coke smelted in an electric furnace. The content of the main component silicon is about 98%, and the other impurities are iron, aluminum, calcium, etc.
In industry, silicon metal is usually produced by reducing silicon dioxide by carbon in an electric furnace. Chemical reaction equation: the purity of silicon prepared by SiO2+2C Si+2CO is 97 98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with purity of 99.7~99.8%.
Metal silicon particles: 1-200mm
silicon metal should be used to produce organic silicon, produce high-purity semiconductor materials and prepare alloys with special purposes.
(1) Production of silicone rubber, silicone resin, silicone oil and other silicone.
(2) Manufacture high-purity semiconductors.
(3) Prepare alloy.
(4) It is an excellent antioxidant in refractory and powder metallurgy industries.
Our company can provide various specifications and models of metal silicon blocks, particles and powders according to customer requirements.
ferro silicon nitride powder is applicable to stainless steel smelting, special alloy steel smelting, oriented silicon steel smelting and other casting industries.
As a new type of refractory material, it is applied in the metallurgical field, such as metallurgical furnace body, furnace mouth seal, ironmaking furnace outlet, iron hook amorphous material and nitrogen additive in the steelmaking industry.
Silicon nitride material can be used as abrasive material for abrasive tool manufacturing, and can also be used in chemical fields such as acid resistance, alkali resistance and corrosion resistance.
In terms of steelmaking, granular ferro silicon nitride is mainly used in the production of oriented silicon steel at the initial stage, and it can stably supplement a certain amount of nitrogen for molten steel.
It is formed by obtaining from the hydrogen sulfide and sulfur dioxide and is a product of the purification of coke and natural gases are called gas lump. Most of the produced sulphur is used as raw material for the industrial production of sulfuric acid.
