Boron carbide is a well-known abrasive material and it is third hardest material after diamond and cubic boron nitride. Boron carbide powder finds extensive application as a lapping agent in place of diamond. In the finishing of semi-precious gems such as ruby, synthetic corundum etc., boron carbide powder achieves about 60% of the speed steel ...
Abrasives. There are so many options when it comes to choosing the right blast media for a particular finish. Productivity and cost must be the first consideration when making this decision, although, sometimes a specific finish can only be achieved with a media that may be more expensive than others.

Boron Carbide with its high hardness is widely used in polishing, lapping and drilling of hard metals, corundum, sapphire, glass and ceramics, as well as a loose abrasive in cutting applications such as water jet cutting. It can also be used for dressing diamond tools.
We offer boron carbide blasting nozzles with aluminium coating and 30 mm collar in different versions. As the third hardest material after diamonds and CBN (cubic boron nitride), boron carbide is optimally suited for blasting nozzles used for highly-abrasive agents, such as: corundum, silicon carbide, and aluminium oxide.
A very fine grade of boron carbide might also work, though it would be slower and would require some experimentation. Tumble-polishing corundum is more of an art than a science, so if your first results are not quite what you hoped for, back up to an earlier step and try again! ****

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.
Among abrasives, silicon carbide's hardness is higher than corundum, and ranked below diamond, CBN and boron carbide. Silicon Carbide can used widely in Metallurgy Industry/ Nonmetal foundry/ Fireproof industry and grinding material industry as its Heat- Resistance corrosion resistance abrasion resistance.
Ex. Diamond, Corundum, Emery etc. 2. Synthetic Ex. Carborundum ( SiC), Boron Carbide, Alundum etc. Natural Abrasives 1. Corundum (Al 2 O 3) Ranks next to diamond-Moh's scale-9, Uses In grinding wheels,to grind glass/lens/metals, Ruby lasers 2.
Silicon carbide is an important material in TRISO-coated fuel particles, the type of nuclear fuel found in high temperature gas cooled reactors such as the Pebble Bed Reactor. A layer of silicon carbide gives coated fuel particles structural support and is the main diffusion barrier to the release of fission products.
