Silicon Carbide was first prepared in the early 1800''s. It was in commercial production by 1892, as a powder for grinding and cutting, having a Mohs hardness of 9-10 (almost as hard as Diamond). Nicalon continuous multi-filament tow consists of fine filaments of ultra-fine ß-SiC crystals, giving strong particle bonding.
A feasibility study of brazing silicon carbide to metals - TWI
Silicon carbide, and specifically sintered SiC, retains most of its strength to ~1500 C; in addition, it is a very hard material with good wear characteristics. These factors make it a candidate material for use in many aggressive environments; however it has a low CTE, ~4.5 x 10-6/°C.

"Implant Annealing of Al Dopants in Silicon Carbide …
The goal of this research is to develop a post-implantation annealing process in silicon carbide (SiC). Due to the low diffusivities of dopants in SiC, even at temperatures in excess of 2000°C, diffusion is not a suitable process to achieve selective, planar doping. Ion implantation is therefore the most suitable means for achieving selective doping in SiC crystals. The strong covalent
