· CrAs

CrAs is a chromium arsenide intermetallic compound that forms a metallic ceramic material with relatively high hardness and stiffness. While not widely established in conventional engineering applications, CrAs is primarily investigated in materials research for potential use in high-temperature structural applications, wear-resistant coatings, and semiconductor-related studies due to its transition metal composition and crystallographic properties.
