· JVASP-152834· Th3Au4

Th₃Au₄ is an intermetallic compound combining thorium and gold, representing a high-density metal system with potential utility in specialized applications requiring dense materials. While not widely commercial, this compound belongs to the thorium-gold phase family studied for applications in nuclear technology, radiation shielding, and high-performance alloy development where density and thermal stability are design drivers. The thorium component makes this material of particular interest in nuclear and aerospace contexts, though practical deployment remains limited due to thorium's regulatory classification and the cost of gold.

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.
