Development Overview of Main Application Fields of Silicon Carbide

At present, third-generation semiconductor materials are causing a revolution in clean energy and next-generation electronic information technology. Whether it is lighting, household appliances, consumer electronics, new energy vehicles, smart grids, or military products, there is a great demand for this high-performance semiconductor material.
According to the development of third-generation semiconductors, their main applications are semiconductor lighting, power electronic devices, lasers and detectors, and four other fields.
1. Semiconductor lighting
Among the four application fields, the semiconductor lighting industry has developed the fastest, with a scale of tens of billions of dollars.
2. Power electronic devices
In the field of power electronics, the application of wide bandgap semiconductors is just beginning, with a market size of only a few hundred million US dollars. Its application is mainly concentrated in the field of military cutting-edge equipment and is gradually expanding to the civilian field.
3. Laser and detector
In the field of laser and detector applications, GaN based lasers can cover a wide spectral range, achieving the manufacturing of blue, green, ultraviolet lasers and ultraviolet detection.
4. Other applications
In the cutting-edge research field, wide bandgap semiconductors can be used for solar cells, biosensors, hydrogen production media from water, and other emerging applications. Currently, these hot areas are still in the laboratory research and development stage.
Firstly, in the power industry, silicon carbide is widely used as insulation material for high-voltage transmission lines, heat dissipation material for transformers, and ceramic insulators. Due to its high heat resistance, high voltage resistance, and good insulation performance, it can maintain stable performance in high temperature and high voltage environments, and is known as the basic material of the power industry.
Secondly, in the field of mechanical manufacturing, silicon carbide is widely used in the manufacturing of high-speed milling cutters, grinding wheels and other tools due to its excellent properties such as high hardness, high strength, and high wear resistance, as well as bearings, mechanical seals and other components in high-temperature and high-pressure environments, which has a wide market demand.
In addition, in fields such as metallurgy and chemical engineering, silicon carbide can also be made into stainless steel chemical reactors, high-temperature heat exchangers, and other equipment. In the aerospace field, silicon carbide is also widely used in the manufacturing of high-temperature ceramic composite materials, thruster nozzles, and other fields. It has attracted attention due to its excellent properties such as high strength, high hardness, and high heat resistance
