Green silicon carbide and black silicon carbide are subdivided products of silicon carbide. Green silicon carbide is mainly made of petroleum coke and high-quality silica as its main raw materials. It has a green translucent hexagonal crystal shape and has the advantages of stable chemical properties, high hardness, good thermal conductivity, and good machine performance. In terms of hardness, green silicon carbide has a Mohs hardness of 9.2, second only to boron carbide, cubic boron nitride and diamond.

During the production process, green silicon carbide has higher requirements on the purity of raw materials. my country is rich in silica resources, widely distributed and relatively concentrated. At present, the number of silica mines in my country has exceeded 150.0, mainly distributed in Liaoning, Jiangxi, Anhui, Hunan, Sichuan, Fujian, Qinghai and Shandong. According to statistics from the Ministry of Natural Resources, my country’s total reserves of silica for metallurgy, silica for glass and silica for cement reached 2.36 billion tons in 2020. Benefiting from the sufficient supply of raw materials, my country’s green silicon carbide industry has developed rapidly.

According to the “2022-2026 China Green Silicon Carbide Market Feasibility Research Report released by the Industrial Research Center, in recent years, my country has The output of green silicon carbide continues to increase. According to statistics from the China Machine Tool Industry Association, my country’s green silicon carbide output will reach 110,000 tons in 2021, a year-on-year increase of 4.8%. At present, my country’s green silicon carbide production capacity is concentrated in Xinjiang. In 2021, my country’s Xinjiang green silicon carbide output exceeded 100,000 tons, accounting for 90.9% of the country’s total output. Affected by the international situation, the increase in production costs has driven the price of green silicon carbide in my country to continue to rise. In April 2022, the price of green silicon carbide in my country exceeded 14,000 yuan/ton, setting a record high.

Green silicon carbide is mainly used as metallurgical raw materials, abrasives, functional ceramics and advanced refractory materials. It is widely used in the fields of semiconductor manufacturing, abrasive tool production, non-ferrous metals, building materials and photovoltaic power generation. In the field of photovoltaics, green silicon carbide can be used in cutting cutting materials such as monocrystalline silicon, polycrystalline silicon and quartz crystal. Green silicon carbide for silicon wafer wire cutting is an important raw material for the production of solar cell silicon wafers. It has strong cutting ability and excellent thermal conductivity. In recent years, with the continuous breakthroughs in technology, the application demand of green silicon carbide in my country’s petrochemical industry, sandblasting and rust removal, superconducting materials, jewelry and jade and other fields has been growing.

In terms of market competition, my country is the world’s largest producer of green silicon carbide, with many manufacturers, including Xinjiang Tianhongji Silicon Industry, Xinjiang Kuitun Longhai Silicon Industry, Zhengzhou Xinli Wear-Resistant Materials, Shanghai Silicon Industry Group, Shandong Jinmeng New Materials wait.

Industry analysts said that as a third-generation semiconductor material, silicon carbide industry prosperity continues to increase. Different products, with their advantages such as high hardness and good wear resistance, the industry has gained huge room for development. As the scope of applications continues to expand, the market demand for green silicon carbide in high-tech industries continues to grow, which will bring broad prospects for the development of the industry.
