In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder. As the lightest element of the boron group it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral sodium borate, and the ultra-hard crystals of boron carbide and boron ...
Real-time boron powder injection is an advanced technique that offers several advantages over traditional boronization. This method involves injecting submillimeter boron powder directly into the plasma during operation, where it evaporates and deposits a thin boron layer on plasma-facing surfaces.

Amorphous powder boron and polycrystalline β-rhombohedral boron are the most common forms. The latter allotrope is a very hard [ n 1 ] grey material, about ten percent lighter than aluminium and with a melting point (2080 °C) several hundred degrees higher than that of steel.
Boriding, also called boronizing, is the process by which boron is added to a metal or alloy.It is a type of surface hardening.In this process boron atoms are diffused into the surface of a metal component.
Ferroboron (CAS Registry Number 11108–67-1) is a ferroalloy of iron and boron with boron content between 17.5 and 20%.[1]It is manufactured either by carbothermic reduction of boric acid in an electric arc furnace together with carbon steel, or by the aluminothermic reduction of boric acid in the presence of iron.

A schematic of borocarbonitride (BCN) Borocarbonitrides are two-dimensional compounds that contain boron, nitrogen, and carbon atoms in a ratio BxCyNz. [1] [2] Borocarbonitrides are distinct from B,N co-doped graphene in that the former contains separate boron nitride and graphene domains as well as rings with B-C, B-N, C-N, and C-C bonds. [3]
