High quality silicon carbide materials and components you can count on. Silicon carbide is a synthetic material that exhibits high performance characteristics including: high hardness approaching that of diamond, high strength (gains strength at temperature), excellent chemical resistance, excellent thermal shock resistance and excellent wear resistance.
The differences in material properties between silicon carbide and silicon limit the fabriion of practical silicon unipolar diodes (Schottky diodes) to a range up to 100-150 V, with a relatively high on-state resistance and leakage current.
Prices of China-made silicon carbide (SiC), a material used in slicing solar-grade silicon ingots, have increased by 10% to NT$140-200 (US$4.4-6.3)/kg, according to sources with Taiwan-based
Silicon carbide, chemical formula SiC, is a covalent bond material. C and Si belong to the same family, all have a tetravalent bond, while Si also has metal properties. Its structure has the mesh shape and body shape and has high strength in nature, so the properties of silicon carbide material include high-temperature strength, wear-resistant, corrosion-resistant, high thermal conductivity
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 sililcon carbide up to 3.5 m in diameter, and several telescopes are already equipped with SiC optics.
