Chemical silicon is the manufacturing of silicone and polysilicon for silicon metal. From a worldwide perspective, the consumption of metallurgical silicon nearly use in chemical silicon consumption, but with the steady improvement of science and technology, the chemistry of silicon used in the field of organic silicon and silicone mold semiconductor production is proceed to broaden, and is broadly used in the manufacturing of organosilicon monomer and polymer silicone oil, silicone rubber, silicone resin buildings corrosion, waterproofing brokers, they have a high temperature, electrically greatest edge, resistance to radiation, water and different distinctive properties. Electrical, aerospace, machinery, chemicals, pharmaceuticals, protection, building section. Greater than 95% of the integrated circuit core is fabricated from semiconductor silicon, semiconductor is a pillar of the contemporary data industry. “Information superhighway” in numerous functions in the fiber-optic cable fiber optics, silicone mold silicon metallic for the production of raw materials. Chemistry of silicon widely used as a excessive-tech fields, and an important basic industries, consumption growth is stabilizing.
The metal powder provider use quartz rock as uncooked materials, low-ash carbonaceous materials as reductant to produce chemical steel silicon. Electric furnace produce chemical silicon, the uncooked materials primarily silica and carbon supplies. Carbon uncooked material again petroleum coke high quality anthracite or charcoal, can also be blended with a component, to extend the cost resistance. If you have any queries concerning where and how to use silicone mold – https://bbs.now.qq.com/home.php?mod=space&uid=1107202,, you can call us at our own web site. Uncooked supplies require needed purity, good response, so as to attain the product specifications; decreasing agent has a special reaction, as a way to have an ample response with quartz; furnace burden with completely different elements, and with completely different granularity, as a way to through the ample coordination make the electric furnace with good impact.
The technique of silicon oxide mineral smelting metallic silicon is a no slag process, chemical silicon smelting is through stringent alternative of silica, not solely the content material of impurities is much less, but in addition requires a high mechanical strength, and adequate thermal stability, a suitable particle measurement composition. Chemical silicon smelting is best to decide on silica. The natural form of silicon oxide or exist in independent 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 within the silicon oxide mineral and adhesive materials in the smelting course of and some completely restored, and a few components are restored, some compound kind coming into the product silicon or born slag. This is not only will increase vitality consumption, decrease product high quality, cause difficulties to the smelting course of.
Silica into the furnace is required to have a certain particle size. Silica particle dimension is an important strategy of smelting. Silica appropriate particle measurement affected by silica sorts, furnace capability, maneuvering conditions, as properly as the decreasing agent and the particle dimension and other elements, it is set to the precise conditions of smelting. Carbonaceous reducing agent, the primary reducing agent of chemical silicon smelting, petroleum coke, bituminous coal, charcoal. So as to extend the burden of the resistivity and improve the chemical activity, additionally with gas coal, silica naphthalene, blue, charcoal, semi-coke, low temperature coke, pieces of wooden. Within the chemical elements of the carbonaceous decreasing agent, primarily must be considered fastened carbon, ash, risky matter and moisture. Common requirements for fixed carbon, reduce the reductant complete required, thus much less ash into the impurities, a corresponding discount in the quantity of slag, decreased power consumption, reduced chemical silicon impurity content material. The resistivity of the carbonaceous decreasing agent to be giant, the porosity to be high. The furnace burden resistivity depends primarily on the carbonaceous reductant. The higher carbonaceous reductant resistivity, the higher chemical activity, and the excessive restoration charge of the silicon power.
