Silicon carbide - Wikipedia

Silicon carbide, also known as carborundum /kɑːrbəˈrʌndəm/, is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions requiring high endurance, …

Finding crystals for a crystal radio? : amateurradio

since the silicon carbide rectifier is essentially the same as a carborundum crystal, the diode needs a slight forward bias to bring it into near-conduction (this makes it much more sensitive). Marconi receivers in 1917 had a bias battery for the crystal mount, and the bias could be set for maximum sensitivity once a sensitive spot on the
