Silicon Carbide - Overview
Silicon carbide, also known as SiC, is a semiconductor base material that consists of pure silicon and pure carbon. You can dope SiC with nitrogen or phosphorus to form an n-type semiconductor or dope it with beryllium, boron, aluminum, or gallium to form a p-type semiconductor.

Application of Silicon Carbide
Silicon Carbide Used in Semiconductors
Silicon carbide becomes a semiconductor when dopants are added to it. Dopants like boron and aluminum added to silicon carbide make it become a p-type semiconductor. On the other hand, dopants such as nitrogen and phosphorus added to silicon carbide make it become an n-type semiconductor. You can read this post for more information about the differences between p-type semiconductors & n-type semiconductors.
Silicon Carbide Used in Abrasives
Silicon carbide is commonly used as an abrasive because of how hard it is. It is used in the manufacture of grinding wheels, cutting tools, and sandpaper. Silicon carbide abrasives are usually cheaper than other abrasives of similar quality. The abrasives are used to grind materials such as steel, aluminum, cast iron, and rubber.
Silicon Carbide Used in Electric Vehicles
Silicon carbide is a better choice over silicon for powering electric vehicles. Electric vehicles powered by silicon carbide are highly efficient and cost-effective. At present, many well-known companies have used silicon carbide to improve efficiency and range when manufacturing electric vehicles, such as Tesla.
Silicon Carbide Used in Jewelry
Structurally similar to diamond, yet more lustrous, cheaper, more durable, and lighter than diamond, silicon carbide is a well-deserved alternative to diamond in the jewelry industry.
Craftsmanship of Silicon Carbide
The simplest silicon carbide manufacturing method involves melting silica sand and carbon, such as coal, at high temperatures―up to 2500 degrees Celsius. Darker, more common versions of silicon carbide often include iron and carbon impurities, but pure SiC crystals are colorless and form when silicon carbide sublimes at 2700 degrees Celsius. Once heated, these crystals deposit onto graphite at a cooler temperature in a process known as the Lely method.
Lely method: During this process, a granite crucible heats to a very high temperature, usually by way of induction, to sublimate silicon carbide powder. A graphite rod with lower temperature suspends in the gaseous mixture, which inherently allows the pure silicon carbide to deposit and form crystals.
Chemical vapor deposition: Alternatively, manufacturers grow cubic SiC using chemical vapor deposition, which is commonly used in carbon-based synthesis processes and used in the semiconductor industry. In this method, a specialized chemical blend of gases enters a vacuum environment and combines before depositing onto a substrate.
Both methods of silicon carbide wafer production require vast amounts of energy, equipment, and knowledge to be successful.
