A different grit on each side enables two-step sharpening with one stone. First sharpen your blade with a lower grit, then sharpen again with a finer (higher) grit until the desired edge is achieved. The silicon carbide abrasive cuts quickly with light pressure. Also known as Crystolon stones.
Study on the Gel Casting Process of Silicon Carbide
Silicon carbide possess high performances such as high hardness and strength, oxidation and high temperature resistance, high thermal conductivity and low thermal expansion coefficient. Widely used methods of molding green body for sintered pressureless bonded silicon carbide comprise dry pressing molding and casting molding.

Carbide - Wikipedia
Boron carbide, B 4 C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms. In this respect boron carbide is similar to the boron rich borides. Both silicon carbide (also known as carborundum) and boron carbide are very hard materials and refractory. Both materials are important industrially.

Hints for Neutrino-process Boron in Presolar Silicon
We have studied more than 1000 presolar silicon carbide (SiC) grains from the Murchison CM2 chondrite for C- and Si-isotopic compositions. Twelve SiC X grains, characterized by strong enrichments in 28 Si and believed to originate from Type II Supernovae (SNeII), were also measured for Li- and B-isotopic compositions. None of these grains show resolvable isotope anomalies in Li or B.

Silicon carbide | chemical compound | Britannica
Until the invention of boron carbide in 1929, silicon carbide was the hardest synthetic material known. It has a Mohs hardness rating of 9, approaching that of diamond. In addition to hardness, silicon carbide crystals have fracture characteristics that make them extremely useful in grinding wheels and in abrasive paper and cloth products.

Appliions of Boron Carbide Machining
However, one of the drawbacks of Boron Carbide is that it begins to oxidise at temperature above 500°C unlike Silicon Carbide where the formation of an oxide layer of Silicon dioxide, retards high temperature oxidation. In addition, due to the relatively low thermal conductivity of Boron Carbide it displays poor thermal shock resistance.
