Chemical silicon is the production of silicone and polysilicon for silicon metal. From a worldwide perspective, the consumption of metallurgical silicon almost use in chemical silicon consumption, but with the steady growth of science and expertise, the chemistry of silicon utilized in the field of organic silicon and semiconductor manufacturing is proceed to broaden, and is widely used within the production of organosilicon monomer and polymer silicone oil, silicone rubber, silicone mold silicone resin buildings corrosion, waterproofing brokers, they have a high temperature, electrically greatest edge, resistance to radiation, water and different distinctive properties. Electrical, aerospace, equipment, chemicals, pharmaceuticals, defense, construction part. More than 95% of the built-in circuit core is manufactured from semiconductor silicon, semiconductor is a pillar of the contemporary information trade. «Info superhighway» in a large number of applications within the fiber-optic cable fiber optics, silicone gadget silicon metallic for the production of uncooked supplies. Chemistry of silicon broadly used as a high-tech fields, and an important basic industries, consumption growth is stabilizing.
The metallic powder provider use quartz rock as uncooked supplies, low-ash carbonaceous materials as reductant to supply chemical metallic silicon. Electric furnace produce chemical silicon, the uncooked materials mainly silica and carbon materials. Carbon uncooked material again petroleum coke high quality anthracite or charcoal, can be combined with an element, to increase the cost resistance. Raw materials require mandatory purity, good response, in order to realize the product specifications; decreasing agent has a distinct response, in an effort to have an satisfactory response with quartz; furnace burden with totally different components, and with different granularity, with the intention to by way of the sufficient coordination make the electric furnace with good effect.
The strategy of silicon oxide mineral smelting metallic silicon is a no slag process, chemical silicon smelting is thru stringent choice of silica, not solely the content material of impurities is less, but in addition requires a high mechanical strength, and enough thermal stability, an appropriate particle dimension composition. Chemical silicon smelting is better to decide on silica. The natural form of silicon oxide or exist in impartial quartz minerals, or is almost wholly into the rock by the silicon oxide product — silica, or silica morphology sandstone. Manufacturing of chemical silicon containing impurities in the silicon oxide mineral and adhesive material in the smelting process and a few utterly restored, and a few elements are restored, some compound form entering the product silicon or born slag. This is not only will increase energy consumption, decrease product high quality, trigger difficulties to the smelting process.
Silica into the furnace is required to have a certain particle measurement. Silica particle measurement is a vital process of smelting. Silica appropriate particle dimension affected by silica types, furnace capability, maneuvering circumstances, as effectively because the reducing agent and the particle size and different factors, it is determined to the particular circumstances of smelting. Carbonaceous decreasing agent, the primary reducing agent of chemical silicon smelting, petroleum coke, bituminous coal, charcoal. In order to increase the burden of the resistivity and increase the chemical exercise, additionally with gas coal, silica naphthalene, blue, charcoal, semi-coke, low temperature coke, pieces of wooden. In the chemical parts of the carbonaceous lowering agent, primarily must be thought of fastened carbon, ash, unstable matter and moisture. Common requirements for mounted carbon, cut back the reductant total required, thus much less ash into the impurities, a corresponding discount in the amount of slag, lowered energy consumption, decreased chemical silicon impurity content material. The resistivity of the carbonaceous lowering agent to be large, the porosity to be excessive. The furnace burden resistivity relies upon totally on the carbonaceous reductant.

The higher carbonaceous reductant resistivity, the higher chemical activity, and the high recovery price of the silicon energy.
