· Hf1 B6

Hafnium hexaboride (HfB₆) is a refractory ceramic compound combining hafnium metal with boron in a hexaboride crystal structure, belonging to the family of transition metal hexaborides. This material is primarily of research and emerging industrial interest for ultra-high-temperature applications where exceptional thermal stability and hardness are required, particularly in aerospace and advanced thermal protection systems where conventional ceramics reach their performance 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.
