ceramic

· JVASP-124392· TaHg

TaHg is an intermetallic compound formed from tantalum and mercury, representing a specialized ceramic material with extremely high density. This material exists primarily in research and materials science contexts rather than widespread industrial production, making it notable for fundamental studies of intermetallic phases and their properties. The tantalum-mercury system is of interest in specialized applications requiring dense materials, though practical use is limited by mercury's volatility and toxicity concerns at operational temperatures.

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.
