· JVASP-36379· CaB2

Calcium diboride (CaB2) is a ceramic compound belonging to the metal boride family, characterized by its crystal structure containing boron and calcium atoms. This material is primarily of research and experimental interest rather than established in mainstream industrial production, with potential applications in high-temperature structural applications, wear-resistant coatings, and advanced ceramic composites where its hardness and thermal stability could provide advantages over conventional ceramics.
