Silicon Carbide Ball, SiC Ball

Silicon Carbide (SiC) Ball is a high-performance ceramic ball that is used in various industries for its unique properties. SiC Balls are made of silicon carbide material, which is a high-strength ceramic material that offers excellent hardness, wear resistance, and thermal shock resistance.

SiC Balls have a number of benefits over traditional ball materials like steel or ceramic, including their ability to withstand extreme temperatures and pressures, their resistance to corrosion and abrasion, and their low coefficient of thermal expansion, which makes them ideal for high-temperature applications.

SiC Balls are commonly used in applications where high-performance balls are required, such as bearings, valves, and pumps. They are also used in the semiconductor industry as components for wafer processing equipment.

SiC Balls are available in a variety of sizes and grades to fit different types of machinery, and they can be customized to meet specific application requirements. They are known for their high durability and long lifespan, making them a cost-effective choice for applications that require high-performance, long-lasting balls.

Overall, SiC Balls are an excellent choice for applications that require high-performance, long-lasting balls that can withstand extreme conditions and provide reliable operation.

Silicon Carbide Ceramics Applications

Until the invention of boron carbide in 1929, silicon carbide was the hardest synthetic material known. It has a Mohs hardness rating of 9, approaching that of a diamond. In addition, SiC crystal has fracture characteristics that make them extremely useful in grinding wheels and in abrasive paper and cloth products.

Its high thermal conductivity, together with its high-temperature strength, low thermal expansion, and resistance to chemical reaction and thermal shock, makes silicon carbide valuable in the manufacture of high-temperature bricks and other refractories.

SiC ceramic is also classed as a semiconductor, having an electrical conductivity between that of metals and insulating materials. This property, in combination with its thermal properties, makes SiC a promising substitute for traditional semiconductors such as silicon in high-temperature applications.
