Ca4RhN4

Ca₄RhN₄ is a quaternary ceramic nitride compound combining calcium, rhodium, and nitrogen in a fixed stoichiometric ratio. This is a research-phase material rather than a commercial product, belonging to the family of transition metal nitride ceramics that are investigated for their potential hardness, thermal stability, and electronic properties. The incorporation of rhodium—a precious refractory metal—into the nitride lattice positions this compound as an exploratory candidate for applications requiring extreme thermal resistance or chemically inert surfaces, though its practical viability depends on synthesis cost and scalability.
