The low thermal expansion coefficient, high hardness, rigidity and thermal conductivity make silicon carbide a desirable mirror material for astronomical telescopes. The growth technology ( chemical vapor deposition ) has been scaled up to produce disks of polycrystalline silicon carbide up to 3.5 meters in diameter, and several telescopes like the Herschel Space Telescope are already equipped
Silicon carbide (SiC) ceramics have excellent properties such as oxidation resistance, high-temperature strength, chemical stability, thermal shock resistance, thermal conductivity and good air tightness, which have been widely used in the fields of energy, metallurgy, machinery, petroleum, chemical industry, aviation, aerospace and national defense. Habitually, silicon carbide used in the
For instance, the highest operating temperature of reaction bonded silicon carbide is 1375 C, which is close to the silicon’s melting point. Production The nitrogen-bonded silicon carbide is produced by firing mixtures of high-purity silicon carbide and silicon, or a mineral additive in a nitrogen atmosphere, at high temperature (usually 1350 ºC to 1450 ºC).

Silicon carbide fibers reinforced composites offer good creep-rupture resistance and low thermal permeability & conductivity. These composites can also be engineered to incorporate capabilities for specific temperature, life, stress, and environmental conditions, thereby, driving the composites segment over the forecast period.
AlSiC, pronounced "alsick", is a metal matrix composite consisting of aluminium matrix with silicon carbide particles. It has high thermal conductivity (180–200 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics..
Using silicon carbide instead of silicon in high-voltage devices will let manufacturers replace slow silicon bipolar transistors with For silicon, this thermal failure occurs at around 150 C
Boostec® Silicon Carbide Parts Mersen Boostec offers assistance to its customers for the design of their SiC parts to ensure better feasibility, mitigate risks and also reduce cost and lead times. For some appliions, the silicon carbide can receive a CVD (chemical vapor deposition) coating to give a completely non-porous high-purity SiC surface.
Oxide Bonded Silicon Carbide is designed for exceptional wear and corrosion resistance. It can be formed into very intrie and precise shapes with the Blasch process. Oxytron has desirable refractory and chemical properties.
Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.

The thermal expansion of 6H Silicon Carbide with different dopant concentrations of aluminum and nitrogen was determined by lattice parameter measurements at temperatures from 300 K to 1575 K. All samples have a volume of at least 6 x 6 x 6 mm3 to ensure that
Silicon carbide (SiC) has a range of physical properties that makes it a versatile and useful material. It is one of the hardest materials known, second only to diamond, has a relatively low density (approximately the same as aluminum), good wear and corrosion resistance and low thermal expansion and high thermal conductivity leading to excellent thermal shock resistance.
