Discussion in ' while boron carbide is much less expensive than diamond or CBN, it's still a good deal more expensive than aluminum oxide or silicon carbide. since up to about 400 grit in more pedestrian stones still work pretty effectively on high-vanadium steels due to the small size of theZirconium Carbide Powder / ZrC Powder (ZrC, High Purity 99Zirconium Carbide Powder / ZrC Powder (99.9%, 400-1200nm, Cubic) Zirconium Carbide (ZrC) Nanopowder / Nanoparticles 10wt% Water Dispersion (99+%, 20nm, Cubic) Silicon Carbide Nanopowder SiC Nanoparticles DMSO dispersion,Boron Carbide B4C Nanopowder / B4C Nanoparticles water dispersion,b4c,b4c ceramic,boron carbide,boron carbide ceramicIndicators for boron carbide ceramic.
