· JVASP-19033· SnP7Au3

SnP7Au3 is an intermetallic compound combining tin, phosphorus, and gold—a research-phase material belonging to the family of precious metal phosphides. This compound is primarily of academic interest for studies in layered materials science, as evidenced by its measured exfoliation energy, suggesting potential for producing thin films or two-dimensional structures through mechanical or chemical separation. While not yet established in commercial applications, materials in this compositional family are being explored for advanced electronic, photocatalytic, and thermoelectric applications where the combination of a noble metal (gold) with a p-block element (phosphorus) offers unusual electronic properties.

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.
