· JVASP-40095· CaYHg2

CaYHg₂ is an intermetallic ceramic compound containing calcium, yttrium, and mercury, representing a specialized class of ternary compounds with potential applications in materials research. This is primarily an experimental material studied for its crystal structure and physical properties rather than an established commercial product. The material family is notable in metallurgy and materials chemistry for understanding phase relationships in complex multi-element systems, though industrial adoption remains limited due to the toxicity concerns associated with mercury-containing phases and the specialized synthesis requirements.
