Silicon carbide, which is incredibly hard and heat-resistant, is the key behind optoelectronics. Electroluminescence was first seen in silicon carbide. The material was used in the 1920s for the first LEDs. Silicon carbide LEDs were mass produced in the 1970s. But after that, direct-bandgap semiconductors took over silicon carbide’s role.

The electrical properties of β‐SiC ceramics were found to be adjustable through appropriate AlN –Y 2 O 3 codoping. Polycrystalline β‐SiC specimens were obtained by hot pressing silicon carbide (SiC ) powder mixtures containing AlN and Y 2 O 3 as sintering additives in a nitrogen atmosphere. The electrical resistivity of the SiC specimens, which exhibited n ‐type character, increased
Carbon, carbides, and nitrides are materials having a relatively high emissivity over the entire spectral range. They are important both as a material and as material components of composites for high-temperature appliions, e.g.. in space technology (reusable space transport systems) or energy systems (hot gas turbines). The normal total and spectral emissivities of these three materials
