97 silicon carbide

Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal coke) and wood chips as raw materials through high temperature smelting in a resistance furnace. Silicon carbide can be divided into many categories, which are divided into different types according to different use environments. Generally used in machinery more.

Application value of metal silicon

A large amount of silicon is used for smelting into ferrosilicon alloy as an alloying element in the iron and steel industry, and as a reducing agent in the smelting of many kinds of metals. Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon. Silicon is the raw material of ultra-pure silicon in the electronics industry.

Silicon carbide is mainly reflected in which major fields?

Silicon carbide one-dimensional nanomaterials are generally considered to be an important component of the third-generation wide-bandgap semiconductor materials because of their own microscopic description and crystal structure, which give them more unique and excellent functions and wider application prospects.

Silicon calcium manganese steelmaking deoxidant

The main role of silicon calcium and manganese is deoxyer, thermostat agent and breeding agent. In the steelmaking industry, it is used for deoxidation and temperature increase. Silicon calcium manganese composite silicon, calcium -to -oxygen affinity is very large. It is also very large, and it is easy to remove from dehydration and desulfurization products.

Introduction to Silicon Carbon Alloy

Strictly speaking, silicon-carbon alloy is not a smelting material developed specifically, but a by-product of the production of metallic silicon. Silicon-carbon alloys in steel can play a good role in deoxidation, and silicon-carbon alloys have the functions of inoculants and nodularizers in casting, which is enough to see the importance of silicon-carbon alloys to steel-making and casting.

what is silica fume?

Silica fume is also called micro-silica fume or agglomerated silica fume. When iron alloy is smelting ferrosilicon and industrial silicon (metal silicon), a large amount of highly volatile SiO2 and Si gas is produced in the submerged thermal electric furnace.

What are the advantages of silicon carbon alloys?

Silicon-carbon alloy also has the advantage of slag collection. Putting a certain proportion of silicon-carbon alloy into molten steel can make the oxides in the steelmaking process quickly form agglomeration, which is convenient for filtration treatment, making the molten steel more pure and greatly improving the density and hardness of the steel. .

Ferrosilicon spot, factory direct supply

High-silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low-carbon ferroalloys. Ferrosilicon added to cast iron can be used as an inoculant for ductile iron, which can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the properties of cast iron.

Silicon metal 553 industrial 441

Silicon metal is widely used in refractory materials, powder metallurgy industry, is an excellent antioxidant. Adding silicon metal in refractory can react with oxygen

The silicon metal manufacturer takes you to learn more about the relevant knowledge of silicon metal

silicon metal , also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Metallic silicon is a product smelted from quartz and coke in an electric furnace. The main component of silicon is about 98% (in recent years, 99.99% of Si is also contained in metallic silicon). The remaining impurities are iron and aluminum. , Calcium, etc.
