Industrial Field

I. Basic Properties

1. High Hardness and Wear Resistance
   Silicon carbide has a hardness second only to diamond and ranks high on the Mohs hardness scale. This enables it to perform excellently in application scenarios where resistance to wear and abrasion is required. For example, in grinding and cutting tools, grinding wheels and cutting discs made of silicon carbide can efficiently process various hard materials, and they have a long service life, effectively reducing the costs and time consumption associated with frequent tool replacements.
2. High Thermal Conductivity and High Temperature Resistance
   It has excellent thermal conductivity and can quickly conduct heat while maintaining stable performance under high-temperature conditions. Its high temperature resistance allows it to function normally at temperatures as high as 1500 °C or even higher. This makes silicon carbide an ideal material for the manufacture of high-temperature furnaces, refractory materials, and high-temperature components in aerospace and automotive engines. It helps improve the working efficiency and reliability of these devices and reduces the risks of material deformation and damage caused by high temperatures.
3. Good Chemical Stability
   Silicon carbide is highly resistant to most chemical substances such as acids and alkalis and is not prone to chemical reactions. Whether in the corrosive environment during chemical production processes or in the case of possible chemical erosion of electronic devices, silicon carbide can hold its ground, ensuring the long-term stable operation of related equipment and products and reducing the need for maintenance due to chemical corrosion.

II. Application Areas

1. Abrasive and Grinding Tool Industry
   As the main abrasive component, silicon carbide abrasives are widely used in the manufacturing of products such as sandpaper, grinding wheels, and polishing pastes. Whether it is surface grinding and rust removal in metal processing or the fine polishing of materials such as stone and glass, silicon carbide grinding tools can provide precise and efficient processing results, enabling the surface of workpieces to achieve the desired smoothness and flatness to meet different industrial and decorative requirements.
2. Refractory Material Field
   It is used to manufacture various refractory bricks, refractory linings, etc. In high-temperature industrial processes such as steel smelting, non-ferrous metal processing, and ceramic firing, silicon carbide refractory materials can withstand extreme high temperatures and thermal shocks, effectively protecting the structure of the furnace body, reducing heat loss, improving energy utilization efficiency, and at the same time extending the service life of the furnace, reducing the equipment renewal and maintenance costs for enterprises.
3. Semiconductor and Electronics Industry
   Silicon carbide has unique advantages in power semiconductor devices. Its high breakdown electric field, high electron saturation drift velocity, and other characteristics enable power devices based on silicon carbide to operate at higher voltages, frequencies, and temperatures. Compared with traditional silicon-based devices, they have lower on-resistance and switching losses. These advantages have led to the wide application of silicon carbide power devices in power electronics, electric vehicle charging piles, solar inverters, and other fields. They can effectively improve power conversion efficiency, reduce the size and weight of equipment, and promote the technological upgrading and energy conservation and emission reduction in related industries.
4. Ceramics and Mechanical Engineering Field
   It can be used to manufacture high-performance ceramic structural parts, such as ceramic bearings and ceramic seals. These ceramic components have low density, high strength, high hardness, and good self-lubricating properties. In mechanical engineering, they can significantly reduce the friction coefficient, reduce wear, improve the operating efficiency and reliability of mechanical systems, and are especially suitable for the operation of equipment under harsh working conditions such as high speed, high temperature, and heavy load, extending the maintenance cycle and service life of the equipment.
