Silicon Carbide is very hard. The only two common abrasive materials harder than SiC are diamonds and boron carbide. Due to its much lower cost than diamond or B4C, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts.
Boron Carbide Powder Background. Boron Carbide is a high performance abrasive material with chemical and physical properties similar to diamonds, such as, chemical resistance and hardness. Boron carbide’s extra hardness gives it the nickname “Black Diamond” (It ranks third after diamond and boron nitride) and is one of the leading grinding materials.

SiC Powders are specifically manufactured to be used for general abrasive applications in bonded abrasive tools, lapping and polishing processes. With a lower hardness and abrasive capacity than diamond or boron carbide, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts
Preparation and abrasion properties of eutectic compositions in B4C-SiC-TiB2 system. July 1995; Authors: Yu. P. Udalov. 21.12; Saint Petersburg State Institute of Technology (Technical University)
3M™ Boron Carbide Abrasive Powders are made of high-purity boron carbide, which is sometimes called “black diamond” for its hardness and chemical resistance. 3M boron carbide abrasive powders are suitable for lapping and sawing of a wide variety of technical ceramics (alumina, zirconia or silicon carbide), tungsten carbide, sapphire, synthetic gemstones, and other hard and super hard
Boron carbide (chemical formula approximately B 4 C) 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.
In this study, spark plasma sintering (SPS) technique was used to sinter B4C+9wt%SiC mixture powder at 1750°C under the mechanical load of 60 MPa with 20 min holding time and 100°C/min heating rate.
Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years. Today the material has been developed into a high quality technical grade ceramic with very good mechanical properties. It is used in abrasives, refractories, ceramics, and numerous high
