Silicon Carbide Sintering Furnace with Great Performance
Silicon Carbide (SiC), also known as carborundum, is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. 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. Large single crystals of silicon carbide can be grown by the Lely method and they can be cut into gems known as synthetic moissanite.
Silicon carbide has a variety of uses in different industries.
1. High thermal conductivity
Silicon carbide can withstand very high temperatures without cracking or deforming,
- Ceramic brake discs for the manufacture of sports cars.
- It is also used as armor material for bulletproof vests and sealing ring material for pump shaft seals
One of the main advantages of these applications is the high thermal conductivity of silicon carbide, which is able to dissipate the frictional heat generated at the frictional interface.
2. High surface hardness
Its physical hardness makes it ideal for grinding processes such as grinding, honing, sandblasting and water jet cutting. The high surface hardness allows it to be used in many engineering applications where a high degree of sliding, corrosion and corrosive wear resistance is required, such as components used in pumps, or valves in oil field applications.
In these applications, traditional metal components can exhibit excessive wear rates, leading to rapid failure.
3. The compound's unique electrical properties as a semiconductor make it a
Ideal for ultrafast and high voltage LEDs, MOSFETs and thyristors for high power switching.
4. The material's low thermal expansion coefficient, hardness, rigidity and thermal conductivity make it an ideal mirror material for astronomical telescopes. Silicon carbide fibers called filaments are used to measure gas temperature in an optical technique called filament pyrometers.
5. It is also used for heating elements that need adaptation to extremely high temperatures. It is even used in nuclear power to provide structural support for high-temperature gas-cooled reactors.
