· JVASP-77046· Ca2HgAu

Ca₂HgAu is an intermetallic compound combining calcium, mercury, and gold—a ternary metal system that is primarily of research and academic interest rather than established industrial production. This material belongs to the family of complex intermetallics and has been studied in materials science for understanding phase relationships and crystal structures in multi-component metal systems. While not widely deployed in conventional engineering applications, compounds in this class are investigated for potential use in specialized electronics, thermoelectric devices, or as model systems for studying metal bonding behavior, though practical deployment remains limited by factors such as toxicity concerns (mercury content), scarcity of gold, and challenges in processing and characterization.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
