(1) Ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. (2) Used as an inoculant and spheroidizing agent in the cast iron industry. In the production of nodular cast iron, 75 ferrosilicon is an important inoculant (helping to precipitate graphite) and nodulizer. (3) Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is great, but the carbon content of high-silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or silicon alloy) is a commonly used reducing agent in the production of low-carbon iron alloys in the ferroalloy industry. Ferrosilicon particle size: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized. Packing: Packed in ton bag, 1000kg/bag
High carbon silicon is a new type of alloy used in converters, and can also be called silicon-carbon alloy. It can replace ferrosilicon, silicon carbide, recarburizer, reduce the amount of deoxidizer, used in converter smelting deoxidation alloying process, the effect is stable, steel chemical composition, mechanical properties and internal control quality are better than traditional processes.

Silicon carbide (sic), also known as carborundum, is a compound of silicon and carbon with chemical formula sic. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics  that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light-emitting diodes (leds) and detectors in early radios were first demonstrated around 1907. Today sic is used in semiconductor electronics applications that are high-temperature, high-voltage or both. Large single crystals of silicon carbide can be grown by the lely method; they can be cut into gems known as synthetic moissanite. Silicon carbide with high surface area can be produced from sio2 contained in plant material.

They are widely used for architectural elements, block-outs & hole former, concrete counter tops, flexible form liners, GFRC, manufactured stone veneer, ornamental precast & statuary, stamped & textured concrete, etc. Operation Method: Both pouring and brushing operation methods for our artificial stone casting silicone are available. You can choose the best one as your preference, we can provide thixotropic agent for brushing. Notice What is the hardness should I choose? Normally 20~40 Shore A will be the best, but it also should according to your size and pattern design. Warm Tips: The surfaces with which the material comes in contact must be perfectly clean, free of grease and dry. Close the bottles after use so as not to confuse the cap of the catalyst with that of the base when re-sealing. Be aware of possible cross-contamination; it's highly recommended to use only dedicated gear when processing poly-addition RTV2 silicone rubber (including degassing devices). Be aware that contact with certain material can inhibit the curing of the RTV2 poly-addition silicone rubber. Common contaminants to be avoided include: -Natural or synthetic rubber, vulcanized with sulphur derivatives. -Poly-condensation RTV catalyzed with metallic salts. -PVC stabilizing agents. -Amine cured epoxies. -Sulphur, tin and amines derivatives. -In case of doubt, carry out a small test by pouring the mixture onto a small area of the object.

Black silicon carbide use quartz sand and petroleum coke as the main raw material, smelting the raw material at high temperature electric resistance furnace . Black silicon carbide contains SiC about 95%. The toughness is higher than that of green silicon carbide, black crystals. The microhardness is HV3100-3280kg / mm², brittle and sharp and has a certain electrical conductivity and thermal conductivity. Abrasive made of black silicon carbide is suitable for grinding cast iron, nonferrous metals and rubber, leather, plastic, wood, minerals and other non-metallic materials.
