· JVASP-115485· ScBIr

ScBIr is an intermetallic ceramic compound combining scandium, boron, and iridium, representing a high-performance refractory material in the family of transition metal borides. This material is primarily of research and development interest for extreme-temperature applications where exceptional stiffness and chemical stability are required, particularly in aerospace and high-temperature structural applications. ScBIr and related ternary boride compositions are being investigated as candidate materials for hypersonic vehicle components, rocket engine environments, and advanced thermal protection systems where conventional ceramics or superalloys reach their performance limits.

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.
