Thermal Synthesis - Graphite Products
In the case of beta silicon carbide, two source materials, one carbon and one silicon bearing, are reacted in the furnace to form a unique form of beta silicon carbide. This high-temperature treatment leads to the formation of cubic beta silicon carbide, which differs from the well-known alpha silicon carbide in certain important aspects.

Silicon detector Patented and first manufactured in 1906 by Pickard, this was the first type of crystal detector to be commercially produced. Silicon required more pressure than the whisker contact, although not as much as carborundum. A flat piece of silicon was eedded in fusible alloy in a metal cup, and a metal point, usually brass or gold, was pressed against it with a spring.

Phosphoric acid fuel cells (PAFCs) consist of an anode and a hode made of a finely dispersed platinum alyst on carbon and a silicon carbide structure that holds the phosphoric acid electrolyte. They are quite resistant to poisoning by carbon monoxide but tend to have lower efficiency than other fuel cell types in producing electricity.
