· JVASP-128293· TbTa

TbTa is an intermetallic ceramic compound combining terbium (a rare-earth element) and tantalum, belonging to the family of high-melting-point ceramics and refractory materials. This material is primarily of research and specialized industrial interest, valued for applications requiring extreme temperature stability, corrosion resistance, and chemical inertness in harsh environments. Its combination of rare-earth and refractory metal properties makes it notable for niche high-performance applications where conventional ceramics or superalloys fall short, though limited commercial availability and high material cost restrict broader adoption.

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.
