Carbide Sintering Furnace
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.
