· Ca3Au4

Ca3Au4 is an intermetallic compound combining calcium and gold, belonging to the class of metallic intermetallics that exhibit ordered crystal structures and distinct phase stability. This material is primarily of research and experimental interest rather than established industrial use; intermetallic compounds of this type are investigated for their unique mechanical and thermal properties that can differ significantly from their constituent elements. Potential applications are being explored in high-performance alloy development, electronic materials, and specialized aerospace or chemical-resistant coating systems where the combination of gold's chemical nobility and calcium's reactivity may provide novel functionality.

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.
