CaSiN2

Calcium silicon nitride (CaSiN₂) is a ternary ceramic compound combining calcium, silicon, and nitrogen phases, belonging to the family of nitride ceramics known for high hardness and thermal stability. This material is primarily investigated in research and advanced applications where wear resistance and high-temperature performance are critical, particularly in cutting tools, abrasive applications, and specialized refractory components. CaSiN₂ offers potential advantages over conventional ceramics in applications requiring a balance of hardness, toughness, and thermal shock resistance, though it remains less commercially established than silicon nitride or alumina in mainstream industrial use.
