Calcium hexaboride (CaB₆) is an advanced ceramic compound belonging to the rare-earth hexaboride family, valued for its exceptional hardness and thermal stability. It is primarily used in high-performance applications requiring wear resistance and thermal shock protection, such as cutting tools, abrasive components, and specialized aerospace components. CaB₆ offers an attractive combination of hardness and lower density compared to traditional ceramics like alumina, making it relevant for applications where weight reduction and durability are competing design drivers.

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.
