· SiB3

SiB₃ is a silicon boride ceramic compound belonging to the family of refractory boride materials. It is primarily investigated as an advanced ceramic for extreme-environment applications where high hardness, thermal stability, and chemical resistance are required. While not yet widely commercialized compared to established borides like TiB₂, SiB₃ represents a materials research direction for next-generation thermal and wear-resistant components.

Export Control

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.
