· JVASP-78268· IrC

Iridium carbide (IrC) is a ceramic compound combining iridium metal with carbon, belonging to the refractory carbide family. It is primarily of research and specialized industrial interest due to its exceptional hardness and resistance to extreme temperatures and chemical attack. Applications include high-temperature structural components, wear-resistant coatings, and cutting tool materials where conventional ceramics would fail, though its use remains limited compared to more established carbides like tungsten carbide or titanium carbide due to cost and processing challenges.
