Oxide-bonded SiC Products

Laurel Oxide-bonded SiC Products are a type of materials with excellent performance, integrating the advantages of silicon carbide and oxides. It mainly consists of silicon carbide. Thanks to the characteristics of silicon carbide, such as high hardness, high-temperature resistance, and abrasion and corrosion resistance, this product remains tough in harsh environments. At the same time, the oxide, as a bonding agent, skillfully connects silicon carbide particles closely, further enhancing the integrity and structural stability of the material. It is widely applied in the high-temperature industrial field. For example, it can be used as furnace linings in steel smelting and kiln furniture in ceramic firing. It can withstand high-temperature shocks and chemical corrosion, and also has excellent mechanical properties, effectively extending the service life of equipment and contributing to efficient industrial production.

Product Details






The product characteristics of Oxide-bonded SiC Products are as follows:


1. High Hardness and Abrasion Resistance: Silicon carbide itself has extremely high hardness, second only to a few substances like diamond. Oxide-bonded SiC Products inherit this property, endowing them with outstanding abrasion resistance. They can withstand the scouring and friction of various particles, maintaining the integrity and precision of the surface during long-term use. Thus, they are suitable for working environments with high abrasion intensity, such as ore grinding and material conveying fields.

2. High Temperature Resistance: These products possess excellent high-temperature resistance and can endure the thermal stress and thermal shock in high-temperature environments. In high-temperature industrial furnaces, glass kilns and other high-temperature equipment, they can work stably for a long time without deformation, softening or melting due to high temperature, ensuring the normal operation of the equipment under high-temperature conditions.

3. Corrosion Resistance: They exhibit remarkable corrosion resistance to many chemical substances. Whether it's acid, base or 盐 and other corrosive media, it's difficult for them to cause obvious erosion. This characteristic enables their wide application in corrosive environments like chemical and electroplating industries. They can be used to manufacture the inner linings of reaction kettles, pipelines, valves and other components, effectively prolonging the service life of the equipment and reducing maintenance costs.

4. Good Thermal Conductivity: They have a relatively high thermal conductivity, which allows them to conduct heat quickly and distribute it evenly within the material, reducing local overheating phenomena. In occasions where rapid heat dissipation or uniform heating is required, such as the heat dissipation components of electronic devices and heat treatment equipment, Oxide-bonded SiC Products can play a good role and contribute to improving the performance and efficiency of the equipment.

5. High Strength and Thermal Shock Resistance: Through the binding effect of oxides, the products have relatively high strength and can bear large external forces and pressures. Meanwhile, they also have good thermal shock resistance. That is to say, in the case of rapid temperature changes, the material is not prone to cracks or fractures and can adapt to frequent heating and cooling cycles. They perform excellently in equipment such as continuous casting molds in the steel industry and shuttle kilns in the ceramic industry.
