The Properties and Uses of Silicon Metal

In 1907, the first light emitting diode (LED) was created by applying voltage to a silicon carbide crystal. Through the 1930s silicon use grew with the development of new chemical products, including silanes and silicones. The growth of electronics over the past century has also been inextricably linked to silicon and its unique properties.

Solution Growth of Silicon Carbide Using Fe--Si Solvent

In this paper, we describe the use of liquid Fe–Si alloy as the solvent for the solution growth of silicon carbide (SiC). Iron was chosen owing to the high solubility of carbon in molten iron. The crystal growth of SiC from Fe–40mol% Si solvent on a seed crystal wafer of 6H- or 4H-SiC was carried out at 1,623–1,723K using induction heating.
