Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F).
Silicon carbide charge is sublimated from the bottom of the chamber and deposited on the upper lid, which is cooler. The Lely method , also known as the Lely process or Lely technique , is a crystal growth technology used for producing silicon carbide crystals for the semiconductor industry .
The first light-emitting diodes were produced using silicon carbide from the Acheson process. The potential use of silicon carbide as a semiconductor led to the development of the Lely process, which was based on the Acheson process, but allowed control over the purity of the silicon-carbide crystals.

A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators.
The first Light-Emitting Diode was created in 1927 by Russian inventor Oleg Losev [1], and used silicon carbide as a semiconductor. However, electroluminescence as a phenomenon was discovered twenty years earlier by the English experimenter Henry Joseph Round of Marconi Labs, using the same crystal and a cat's-whisker detector.
Wolfspeed's new 2 million-square foot multi-billion dollar silicon carbide wafer factory in Chatham County, North Carolina, was announced in 2022. Wafers are used for making chips.
Monocrystalline silicon (mono-Si) grown by the Czochralski method is often referred to as monocrystalline Czochralski silicon (Cz-Si). It is the basic material in the production of integrated circuits used in computers, TVs, mobile phones and all types of electronic equipment and semiconductor devices. [6]
