In the field of science and technology and industry, the innovation of materials has always been an important force to promote social progress. Silicon Carbide: A Bright Pearl from Industrial Abrasives to High-Tech Applications

Silicon carbide, also known as carborundum or moissanite, is a high-tech refractory raw material widely used in industrial fields. Today, we focus on a material called silicon carbide (SiC), which plays a pivotal role in modern industry and is expected to play an even more important role in future technological developments. With the continuous progress of science and technology, the use of silicon carbide has expanded from traditional abrasives, wear-resistant agents, abrasive tools, advanced refractory materials and other fields to a wider range of high-tech applications.

Silicon carbide, also known as carborundum or carbon silica, is a kind of quartz sand, petroleum coke (or coal coke) and wood chips (production of green silicon carbide

Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips (the production of green silicon carbide need to add salt) and other raw materials through the resistance furnace high temperature smelting. When the need to add salt) and other raw materials through the resistance furnace high temperature smelting of non-oxide high-tech refractory raw materials. In nature, silicon carbide is also found in the rare mineral moissanite. Although there is also a rare silicon carbide mineral-Moissanite in nature, synthetic silicon carbide has been widely used in industry due to its excellent physical and chemical properties. With its unique physical and chemical properties, this material has become an indispensable and important material in many fields.

The hardness of silicon carbide is second only to diamond, and the microhardness is as high as 2840~3320kg/mm2, so it has high wear resistance and impact resistance.

Silicon carbide has the characteristics of high hardness, strong wear resistance and good thermal stability, and its microhardness can reach 2840~3320 kg/mm, which makes silicon carbide widely used in the fields of abrasives, wear-resistant agents, abrasive tools and so on. In the process of high-speed cutting, grinding and polishing, silicon carbide can effectively improve processing efficiency, reduce tool wear and improve product quality. 2. The specific gravity is 3.20~3.25, and it can withstand high temperatures while maintaining good mechanical properties.

In addition, silicon carbide has excellent thermal stability and oxidation resistance, and can withstand high temperatures and extreme environments. This makes silicon carbide has an important position in the field of advanced refractories. These characteristics make silicon carbide an ideal material in many industrial fields, especially in the fields of abrasives, wear-resistant agents, abrasives and advanced refractory materials. The application of silicon carbide has gone deep into every corner. In ceramics, metallurgy, chemical industry and other industries, silicon carbide is widely used in the manufacture of high-temperature furnaces, refractory bricks, crucibles and other products, providing reliable technical support for these industries.

In terms of abrasives and wear agents, the high hardness and wear resistance of silicon carbide make it an ideal choice for the manufacture of cutting tools, grinding tools and abrasive materials.

In recent years, with the continuous progress of science and technology, the application field of silicon carbide has been further expanded. Whether it is metal processing, ceramic manufacturing or glass processing, silicon carbide provides long-lasting and efficient grinding and cutting performance. In the field of new energy, silicon carbide is used as a substrate material for manufacturing solar cells, which can effectively improve the photoelectric conversion efficiency of solar cells. At the same time, silicon carbide is also widely used in the manufacture of wear-resistant coatings and wear-resistant parts, such as wear-resistant pumps, wear-resistant pipes and wear-resistant valves, which effectively improves the wear resistance and service life of the equipment.

In the field of abrasive tools, silicon carbide is also widely used. In the field of electronic information, silicon carbide is widely used in the manufacture of integrated circuits, semiconductor devices and other products because of its excellent thermal conductivity and electrical properties. It can be used as the main raw material for grinding wheels, abrasive belts and sandpaper, and used for grinding and polishing of metal and non-metallic materials. In the field of aerospace, silicon carbide is used to manufacture key components of high-performance aircraft such as aircraft and rockets because of its light weight, high strength, and high temperature stability. Silicon carbide abrasive tools have won wide recognition in the market for their excellent grinding performance and stable quality.

At the same time, the development and application of green silicon carbide has also contributed to the cause of environmental protection.

In terms of advanced refractories, the high temperature stability and oxidation resistance of silicon carbide make it an ideal material for the manufacture of equipment such as high temperature kilns, heat exchangers and burners. In the production process, by adding salt and other environmentally friendly materials, the energy consumption and pollutant emissions in the production process of silicon carbide can be effectively reduced, and green production can be realized. Silicon carbide refractory materials can withstand high temperatures without softening, effectively protecting equipment from thermal damage, while reducing energy consumption and maintenance costs. This move is not only conducive to the sustainable development of the silicon carbide industry, but also makes a positive contribution to the global environmental protection cause.

In addition, silicon carbide also shows great potential in the field of fine ceramics.

Looking to the future, with the continuous progress of science and technology and the continuous expansion of silicon carbide applications, silicon carbide industry will usher in a broader space for development. We expect that silicon carbide can play an important role in more fields and make greater contributions to the progress of science and technology and the improvement of the quality of life of mankind. Fine ceramics have become the key materials in many high-tech fields because of their high strength, high hardness, high wear resistance and good chemical stability.

In short, silicon carbide as an important high-tech refractory raw materials, its application has been from the traditional abrasives, wear-resistant agents, abrasives, advanced refractory materials and other fields to expand to a broader high-tech applications. As one of the main raw materials of fine ceramics, silicon carbide provides a rich choice for the preparation of ceramics and promotes the innovation and development of the ceramic industry. The excellent performance and wide application of silicon carbide not only provide strong support for the development of various industries, but also make important contributions to the progress and development of human society.
