· Ca5Au2

Ca5Au2 is an intermetallic compound composed of calcium and gold, belonging to the class of binary metallic systems. This material is primarily of research and academic interest rather than established industrial use, representing fundamental studies in phase diagrams and crystal chemistry of earth-abundant metal–precious metal combinations. The material family of calcium–gold intermetallics has potential relevance in specialized applications requiring high-density materials or in materials discovery programs exploring novel alloy systems, though commercial or engineering adoption remains limited.

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.
