Silicon Nitride (Si3N4) Properties and Appliions
Reaction bonded silicon nitride is made by direct nitridation of a compacted silicon powder, and because of the difficulty of ensuring complete reaction, it is hard to achieve a high component density. Usual densities are in the range 2300 - 2700kg.m-3 compared with 3200kg.m-3 for hot pressed and sintered silicon …

Silicon Carbide SiC Material Properties - Accuratus
2016-7-29 · Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.

2020-4-8 · 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.
