MgB₄ is a magnesium boride ceramic compound belonging to the boride family of refractory materials. It is primarily of research and specialized industrial interest for high-temperature applications where chemical stability and hardness are required, particularly in wear-resistant coatings, refractory linings, and potential semiconductor applications. The material is notable for its thermal stability and resistance to oxidation at elevated temperatures, making it an alternative to other boride ceramics in extreme-environment settings, though commercial adoption remains limited compared to established alternatives like tungsten carbide or alumina.
