Si2 B2

Si₂B₂ is an experimental binary ceramic compound in the silicon-boron system, representing a potential hard ceramic material combining silicon and boron in a specific stoichiometric ratio. This composition lies within research into ultra-hard and refractory ceramics, though Si₂B₂ itself remains primarily a laboratory-phase material rather than a commercialized engineering ceramic. Interest in silicon-boron compounds centers on their potential for high-temperature applications, abrasive uses, and semiconductor or thermal management contexts where extreme hardness and chemical stability are valuable.
