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.
Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
Properties of Polysilanes
Polysilanes are important precursors to silicon carbide (fibers). Industrial silicon carbide is typically produced by the Wurtz coupling method where an organohalosilane such as dimethyldichlorosilane is reacted with molten sodium metal to form polydialkylsilane which is then converted to a polycarbosilane:
