Read: 131

Silicon carbide is made of carbon and silicon raw materials heat treatment, with high hardness, high strength, high temperature resistance, corrosion resistance and other characteristics, so it is widely used in the field of casting.


(1) As an abrasive, it can be used as an abrasive tool, such as grinding wheel, whetstone, grinding head, sand tile, etc.


(2) As a metallurgical deoxidizer and high temperature resistant material.


(3) High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.

Main Applications: For 3-12 inch monocrystalline silicon, polysilicon, potassium arsenide, quartz crystal and other wire cutting. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials. It can also be used in semiconductors, lightning rods, circuit components, high temperature applications, ultraviolet detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, fine wire pyrometers, ceramic films, cutting tools, heating elements, nuclear fuel, jewelry, steel, protective gear, catalyst support and other fields.

The advantages of silicon carbide in the field of casting

  1. Good high temperature resistance

In the field of casting, it is often necessary to deal with high-temperature materials, such as molten aluminum. Silicon carbide has high temperature resistance and can withstand wear and corrosion at high temperatures. For traditional ceramic products, cracking and deformation are easy to occur at high temperatures, and silicon carbide can avoid these problems.

  1. Strong corrosion resistance

Corrosive materials are often encountered in the casting field, such as acidic and alkaline materials. Silicon carbide has corrosion resistance and can be used for the treatment of most corrosive materials.

  1. Long life

Compared with traditional ceramic materials, silicon carbide has a longer service life. This is because of the hardness of silicon carbide, good wear resistance, not easy to damage.

  1. Cost effective

Although the price of silicon carbide is higher, it still has a cost-effective advantage compared with traditional ceramic materials. This is because silicon carbide has better performance in terms of service life and performance.
