Green silicon carbide (SiC) is an important industrial material that has attracted widespread attention for its excellent physical and chemical properties. It is smelted in a high-temperature resistance furnace with petroleum coke and salt as the main raw materials. Compared with black silicon carbide, green silicon carbide has higher purity, greater hardness, and better thermal conductivity and electrical conductivity. This makes green silicon carbide show a wide range of application potential in many fields.
Characteristics of green silicon carbide
High hardness: The hardness of green silicon carbide is second only to diamond and boron nitride, making it an ideal abrasive for processing various hard materials.
Self-sharpening: During the grinding process, green silicon carbide can maintain a sharp cutting edge, so it is often used to process materials such as cemented carbide, titanium alloy and optical glass.
Good thermal conductivity: Its thermal conductivity is more than twice that of traditional silicon carbide, which makes it promising in high-temperature heat dissipation and thermal conductivity applications.

Application fields
The application fields of green silicon carbide are very wide, mainly including the following aspects:
Abrasives and grinding tools: Due to its high hardness and self-sharpening properties, green silicon carbide is widely used in the manufacture of grinding tools such as grinding wheels, sandpaper, and sandblasting media. In the manufacture of grinding tools, it is often used in products such as resin grinding wheels, ultra-thin cutting discs, and diamond grinding discs.
Photovoltaic and semiconductor industries: Green silicon carbide plays an important role in the manufacture of solar panels and semiconductor devices. It can improve the efficiency of solar panels and is used to manufacture high-performance electronic devices.
Wear-resistant materials: Due to its excellent wear resistance, green silicon carbide is widely used in wear-resistant materials and high-temperature structural materials, such as in the aerospace and automotive industries.
Energy storage: In the manufacture of lithium-ion batteries, green silicon carbide can be used to increase the energy density of batteries, thereby improving the overall performance of batteries.
Production process
The production process of green silicon carbide mainly includes steps such as raw material preparation, high-temperature smelting, and post-processing. First, petroleum coke is mixed with salt, and then high-temperature smelting is carried out in a resistance furnace to obtain green silicon carbide with higher purity. After crushing, grinding, grading and other processes, products of different specifications are finally formed, such as segmented sand, granular sand and micro powder.
Future Outlook
With the increasing global demand for energy-saving, environmentally friendly and high-efficiency products, the market demand for green silicon carbide continues to grow. In the fields of electric vehicles, renewable energy and smart grids, SiC materials are widely used in power devices and charging piles due to their high thermal conductivity, high temperature resistance and low loss characteristics. For example, electric vehicle inverters using silicon carbide power devices can significantly improve energy conversion efficiency and reduce energy consumption, thereby extending the vehicle’s range24.
Technological Progress and Innovation
Green silicon carbide technology has made significant progress in the past few years. With the continuous improvement of production processes and technological innovation, the performance of SiC materials has been greatly improved. Especially in high temperature and high voltage environments, SiC shows better stability and efficiency than traditional silicon-based semiconductors. This advantage makes SiC also show great potential in fields such as high-frequency communications, solar inverters and military applications.
Challenges of Sustainable Development
Although the green silicon carbide industry has broad prospects, it also faces some challenges. For example, problems such as fluctuations in raw material prices and intensified market competition may affect the development of the industry. In addition, although the production cost of SiC devices is gradually decreasing, it is still higher than that of traditional silicon devices, which may limit its popularity in some fields.
In general, the green silicon carbide industry is in a stage of rapid development. With the continuous growth of market demand, the continuous improvement of technology level and the strengthening of policy support, it is expected that there will be a broader development space in the future. Especially in the fields of electric vehicles, photovoltaic power generation and smart grids, green silicon carbide will play an increasingly important role. Through continuous innovation and optimization of production processes, green silicon carbide is expected to become an important force in promoting global green transformation and contribute positive forces to achieving sustainable development goals.
In summary, as a new type of efficient and environmentally friendly material, green silicon carbide will play an increasingly important role in the future development of science and technology. With the maturity of technology and the expansion of market demand, we can expect the green silicon carbide industry to usher in a better development prospect.
