· JVASP-128250· HoTa

HoTa is a ceramic compound composed of holmium and tantalum, belonging to the family of refractory intermetallic ceramics. These materials are investigated for extreme-environment applications where conventional ceramics or metals fall short, particularly in aerospace and high-temperature nuclear contexts. HoTa is notable as a research-phase material offering potential for ultra-high-temperature structural applications, though it remains primarily in development rather than widespread industrial deployment.

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.
