Chemical silicon is the production of silicone and polysilicon for silicon metal. From a world perspective, the consumption of metallurgical silicon almost use in chemical silicon consumption, but with the continuous development of science and expertise, the chemistry of silicon utilized in the field of natural silicon and semiconductor production is continue to broaden, and is extensively used within the manufacturing of organosilicon monomer and polymer silicone products oil, silicone mold rubber (http://Zoe-beauty.be), silicone resin buildings corrosion, waterproofing brokers, they've a excessive temperature, electrically finest edge, resistance to radiation, water and other distinctive properties. Electrical, aerospace, machinery, chemicals, pharmaceuticals, defense, development part. Greater than 95% of the integrated circuit core is made of semiconductor silicon, semiconductor is a pillar of the contemporary data trade. "Information superhighway" in a lot of applications within the fiber-optic cable fiber optics, silicon steel for the production of uncooked supplies. Chemistry of silicon broadly used as a excessive-tech fields, and an important primary industries, consumption progress is stabilizing.
The steel powder provider use quartz rock as raw materials, silicone rubber low-ash carbonaceous materials as reductant to supply chemical metallic silicon. Electric furnace produce chemical silicon, the raw supplies mainly silica and carbon materials. Carbon raw material again petroleum coke high quality anthracite or charcoal, can be blended with a part, to increase the charge resistance. Raw materials require obligatory purity, good response, in order to realize the product specifications; lowering agent has a unique response, to be able to have an adequate response with quartz; furnace burden with different substances, and with completely different granularity, in an effort to by the enough coordination make the electric furnace with good impact.
The process of silicon oxide mineral smelting metallic silicon is a no slag course of, chemical silicon smelting is thru stringent alternative of silica, not solely the content material of impurities is much less, but additionally requires a excessive mechanical energy, and ample thermal stability, an acceptable particle dimension composition. Chemical silicon smelting is better to choose silica. The natural type of silicon oxide or exist in impartial quartz minerals, or is nearly wholly into the rock by the silicon oxide product - silica, or silica morphology sandstone. Manufacturing of chemical silicon containing impurities within the silicon oxide mineral and adhesive material within the smelting process and a few completely restored, and a few elements are restored, some compound kind getting into the product silicon or born slag. This is not only increases power consumption, decrease product high quality, trigger difficulties to the smelting course of.
Silica into the furnace is required to have a certain particle measurement. Silica particle dimension is a crucial strategy of smelting. Silica suitable particle size affected by silica sorts, furnace capacity, maneuvering circumstances, as nicely as the lowering agent and the particle size and other factors, it is decided to the particular conditions of smelting. Carbonaceous decreasing agent, the principle lowering agent of chemical silicon smelting, petroleum coke, bituminous coal, charcoal. In order to increase the burden of the resistivity and increase the chemical activity, also with fuel coal, silica naphthalene, blue, charcoal, semi-coke, low temperature coke, pieces of wooden. Within the chemical components of the carbonaceous reducing agent, primarily should be thought of mounted carbon, ash, unstable matter and moisture. Basic necessities for fixed carbon, reduce the reductant complete required, thus much less ash into the impurities, a corresponding discount in the amount of slag, diminished power consumption, diminished chemical silicon impurity content material. The resistivity of the carbonaceous decreasing agent to be giant, the porosity to be excessive. The furnace burden resistivity relies upon primarily on the carbonaceous reductant. The higher carbonaceous reductant resistivity, the higher chemical activity, and the excessive restoration charge of the silicon power.
