Silicon carbide ceramic structural parts are a kind of high-performance ceramic materials with a variety of excellent properties, which are widely used in many fields of modern industry.
Silicon carbide (SiC) is a compound composed of carbon and silicon elements. It is made by melting quartz sand, petroleum coke, wood chips and other raw materials at high temperature. Silicon carbide is relatively rare in nature, but synthetic silicon carbide is widely used due to its excellent physical and chemical properties.
Main features
High hardness: The hardness of silicon carbide ceramics is close to that of diamond, with a Mohs hardness of about 9.5, making it excellent in wear-resistant applications.
High corrosion resistance: It has good resistance to most acids, alkalis, and salts, and is suitable for harsh chemical environments.
High-temperature strength: It can maintain mechanical strength and stability in high-temperature environments, and the operating temperature can reach 1600 to 1700 degrees Celsius.
High thermal conductivity: Silicon carbide has good thermal conductivity and can effectively conduct heat.
Low coefficient of thermal expansion: The size changes less when the temperature changes, reducing the impact of thermal stress on the material.
Exceptional wear resistance: high hardness and low coefficient of friction make it excellent in friction applications.
High strength and low density: It has excellent strength and low density, which is conducive to reducing the weight of equipment, improving stability and service life.
Application field
Mechanical seal: Due to its chemical resistance, high strength, high hardness, and low friction coefficient, it is an ideal material for sealing rings, especially suitable for working environments with high PV values and strong acids and alkalis.
Aerospace: used to manufacture spacecraft structural components, engine components, etc., to improve the performance and service life of spacecraft.
Chemical industry: used to make chemical reactor lining, catalyst carrier, etc., acid and alkali corrosion resistance, wear resistance, high temperature resistance.
Metallurgical field: used to make furnace, furnace tube, etc., to improve the service life and efficiency of metallurgical furnace.
Bulletproof material: Due to its high hardness and low density, it can be used to make bulletproof vests, bulletproof armor, etc.
Optical applications: used in the manufacture of ceramic structures such as precision moving workpiece stages, skeletons, and suction cups in lithography machines.
Silicon carbide ceramic structural parts play an important role in many demanding fields due to their excellent performance.
