The third layer is amorphous tungsten carbide, with a thickness of 400-500 nm. Similar approach was also used in the case of CrC. The first layer, with a thickness up to 80 nm was nanocrystalline chromium, which ensures better cling of CrC to the fiber surface
Silicon carbide (SiC), a stable binary compound made of the earth-abundant elements silicon (Si) and carbon (C), has attracted considerable interest for water splitting because its conduction and valence band positions ideally straddle the water redox potentials.
Silicon carbide ceramics have different properties and appliion fields due to their different preparation processes. It can be used as high temperature structural material, refractory material, mechanical seal wear resistant material, acid and alkali resistant corrosion resistant material and high temperature heat exchange material, etc. due to its excellent properties.

2020/8/18· Silicon carbide (SiC) is a compound of silicon metalloid and oxygen. Typically, SiC is used in the alpha silicon carbide structural form. Silicon carbide is a black, high-hardness ceramic that is usually harder than alumina. Depending on the addition of impurities SiC may be green or black in color. Fully-dense SiC can be transparent (moissanite).
