In the past, designing with silicon carbide also presented challenges, such as special gate-drive requirements, that prevent straightforward drop-in replacement of conventional silicon devices. The reality is somewhat different.
Silicon carbide (SiC) is a synthetic compound which is commercially produced by heating a mixture of metallurgical coke and high-purity silica sand to 2,400° C in an electrical resistance furnace. A method to produce SiC was first discovered in this country by E. G. Acheson in 1891 while studying the reaction of carbon with other materials. The first patent on the manufacture of SiC was
Single crystals of crystalline silicon can be grown with a process known as the Czochralski process. Silicon carbide (SiC) is nearly as hard as diamond and is used as an abrasive. Silicon nitride is used in rotating bearing balls & rollers, cutting tools, engine moving & wear parts, turbine blades, vanes & buckets, metal tube forming rolls & dies, etc.
Silicon carbide is enabling smarter, more efficient power systems. Image source: Littelfuse, Inc SiC is being adopted in several appliions, particularly e-mobility, to meet the energy and cost challenges in the development of high-efficiency and high-power devices.
The global silicon carbide market size is estimated to grow from USD 749 million in 2020 to USD 1,812 million by 2025, at a CAGR of 19.3%. The key factors fueling the growth of this market are the growing demand for SiC devices in the power electronics industry, and increasing investments by industry players to increase SiC production.
