· Ca2 B4 C4

Ca₂B₄C₄ is a quaternary ceramic compound combining calcium, boron, and carbon elements, belonging to the family of boron-carbon ceramics with potential semiconductor or wide-bandgap material characteristics. This material is primarily of research interest rather than established industrial production, explored for high-temperature structural applications, electronic devices, and advanced composites where its thermal stability and hardness could provide advantages over conventional ceramics. Its boron-carbon framework suggests potential relevance to next-generation semiconductor or refractory applications, though practical engineering adoption remains limited pending further development and property validation.
