· JVASP-65127· BeNb4Tl

BeNb4Tl is an intermetallic compound combining beryllium, niobium, and thallium—a rare ternary metal system primarily investigated in materials research rather than established commercial production. This compound belongs to the family of high-melting intermetallics and is of interest to researchers exploring advanced refractory materials and specialized alloy systems, though practical industrial adoption remains limited due to raw material costs, processing complexity, and the toxicity concerns associated with thallium. Engineers would consider this material only in niche research contexts where its unique phase stability or thermal properties offer advantages unavailable in conventional refractory alloys or high-temperature intermetallics.

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.
