· JVASP-122570· Sn7Hg

Sn7Hg is a tin-mercury intermetallic compound classified as a ceramic material, representing a high-density phase that forms in the Sn-Hg binary system. This material is primarily of research and historical interest, particularly in dental amalgam formulations and specialized metallurgical applications where tin-mercury phases provide enhanced mechanical or thermal properties. Its use in modern engineering is limited compared to contemporary alternatives, but it remains relevant in understanding dental composite behavior and in niche applications requiring high-density metallic ceramic phases.

Regulatory Screening

Environmental

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.
