Black boron carbide powder used for additive for sintering silicon carbide parts and diamond tools. nano boron carbide powder used in steel modification component with high boron content. b4c boron carbide powder used for boronizing; boron carbide powder used for tools and machine components ; b4c boron carbide powder used for finishing / lapping
Boron carbide (chemical formula approximately b4c) is an extremely hard boron–carbon ceramic, and covalent material used in tank armor, bulletproof vests, engine sabotage powders, as well as numerous industrial applications. with a vickers hardness of >30 gpa, it is one of the hardest known materials, behind cubic boron nitride and diamond.
Moreover, al 8 b 4 c 7 can function as the sintering additive to improve the sintering property of b 4 c ceramic which could result in higher relative density, lower shrinkage rate and better mechanical properties, compared to that without the addition of al 8 b 4 c 7 [5], [6].
American elements specializes in producing high purity boron carbide powder with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in chemical vapor deposition (cvd) and physical vapor deposition (pvd) processes including thermal and electron beam (e-beam) evaporation, low temperature organic evaporation, atomic layer deposition (ald), metallic-organic and chemical vapor deposition
