Silicon carbide refractroy material is a typical polymorphic compound, which is classified into a large class, refractory silicon carbide has both α-silicon carbide and β-silicon carbide. As a kind of abrasive, α-silicon carbide has two types of black silicon carbide and green silicon carbide. Refractory silicon carbide is the main refractory raw material for the preparation of silicon carbide ceramics. Silicon carbide refractory material is widely used, such as metallurgy, machinery, chemicals, building materials, light industry, electronics, and heating elements. Abrasives can be used as a scavenger, deoxidizer and improver in the metallurgical industry. Silicon carbide can be used as a synthetic carbide tool in machining. The processed silicon carbon plate can be used as a refractory material for ceramic firing. The silicon carbide micropowder produced by the finishing process can be used for coating of high-tech electronic components and far-infrared radiation materials. High purity fine powders are available for coatings in defense industry aerospace vessels. Silicon carbide refractory material is widely used in various economic fields at home and abroad.
Silicon carbide semiconductors can cope with "extreme environments," and it is said that silicon carbide wafers can withstand heat near Venus or the Sun. Previous studies have shown that even at high temperatures of 560 ° C, silicon carbide wafers can operate normally without a cooling device. Refractory silicon carbide wafers have broad application prospects in the field of communications, allowing high definition TV transmitters to provide clearer signals and images. Silicon carbide can also be used in jet and car engines to monitor motor operation. At the same time, it can also be used in space exploration to help nuclear-powered spacecraft perform more complex tasks. French physicists predict that silicon carbide will not be far behind in the field of chip manufacturing.
Industrial Applications of Silicon Carbide Mainly Include the Following
(1) Abrasives of Silicon Carbide
Mainly because silicon carbide has high hardness, chemical stability and certain toughness, silicon carbide can be used in the manufacture of bonded abrasives, coated abrasives and free grinding to process glass, ceramics, stone, cast iron and some non-Iron metal, hard alloy, titanium alloy, high speed steel cutter and grinding wheel.
(2) Refractory Material and Corrosion Resistant Refractory Materials
Mainly because silicon carbide has high melting point (decomposition temperature), chemical inertness and thermal shock resistance, refractory silicon carbide can be used in abrasive and ceramic products in kiln firing kiln and smelting and smelting industrial vertical cylinder distillation furnace. A variety of silicon carbide ceramic products such as silicon carbide bricks, aluminum electrolytic tank linings, crucibles, and small pieces of furnace refractory materials.
(3) Chemical Use of Silicon Carbide Refractory Material
Because silicon carbide can be decomposed in molten steel and reacted with free oxygen and metal oxides in molten steel to form carbon monoxide and silicon containing slag. Therefore, refractory material can be used as a smelting steel purifying agent, that is, as a steelmaking deoxidizer and a cast iron structure modifier. This generally uses low purity silicon carbide to reduce cost. At the same time, it can also be used as a raw refractory material for manufacturing silicon tetrachloride.
(4) Electrical Use of Silicon Carbide Refractory Material
Used as heating element, non-linear resistance element and high temperature semiconductor material. Heating elements such as silicon carbon rods (suitable for various electric furnaces operating at 1100 to 1500 °C), non-linear resistance elements, and various types of lightning protection valves.
(5) Others
It is formulated into a far-infrared radiation coating or a far infrared radiation dryer for making silicon carbide silicon plates.
