Calcium selenate (CaSeO₄) is an inorganic ceramic compound belonging to the sulfate/selenate family of materials. It is a brittle, crystalline ceramic with moderate stiffness and relatively high elastic compliance, making it useful in specialized applications where chemical stability and thermal properties are prioritized over mechanical strength. This material is primarily explored in research contexts for applications requiring selenate-bearing ceramics, particularly in nuclear waste immobilization, radiation shielding, and specialized refractory systems where selenium compounds must be chemically locked into a stable ceramic matrix to prevent leaching.
