· JVASP-67411· YTaBe2

YTaBe2 is an advanced ceramic compound in the yttrium tantalum beryllide family, combining rare-earth and refractory metal elements with beryllium. This is a research-stage material investigated for extreme-environment applications where conventional ceramics fall short, particularly in systems requiring simultaneous thermal stability, mechanical stiffness, and resistance to harsh chemical or irradiation conditions. The material represents the broader push toward ultra-high-temperature ceramics and advanced composites for next-generation aerospace, nuclear, and specialized defense systems.

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.
