Fused silica grades termed UV grade are better controlled from these metals, and so they transmit further into UV ranges. But their drawback is OH caused absorption, especially at 2.2um and 2.7um. All SiO2 glasses share some properties, including extreme hardness, very low thermal conductivity, low thermal expansion, and a wide range of optical transmission from UV to IR.

Silicon Carbide Fibre | Materials Hub

Silicon carbide (SiC), also known as carborundum is an exceedingly hard, synthetically produced crystalline compound of silicon and carbon. It occurs in nature as the extremely rare mineral Moissanite. Until 1929, silicon carbide was the hardest synthetic material known. It has a hardness rating of 9, close to that of diamond. In addition to hardness, […]

The high thermal conductivity enables SiC-based devices to operate at extremely high power levels whilst still being able to dissipate the large amounts of generated excess heat. SiC devices can operate at high frequencies, such as radio and microwave frequency ranges, due to the larger saturated electron drift velocity, which is two to two-and-a-half times larger than that of Si [23].
