· 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.
