· JVASP-39260· HoVB4

HoVB4 is a refractory intermetallic compound combining holmium, vanadium, and boron, belonging to the metal boride family. This material is primarily of research interest for high-temperature structural applications where exceptional hardness and thermal stability are required. While not yet widely commercialized, holmium-based borides are investigated for potential use in extreme-environment aerospace and energy systems where conventional superalloys reach their limits.

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.
