Recrystallized Silicon Carbide Powder

Recrystallized Silicon Carbide Powder

Recrystallized Silicon Carbide Powder is a high-quality powder that is specifically designed for use in the production of high-performance ceramics. It is made by heating a mixture of silicon carbide powder and a small amount of additive to high temperatures in a specialized furnace. The process causes the silicon carbide particles to recrystallize, resulting in a powder with high purity and excellent mechanical properties.

The Recrystallized Silicon Carbide Powder has a high degree of purity and a unique crystal structure that gives it superior mechanical properties, such as high strength, hardness, and wear resistance. This makes it an ideal material for use in a wide range of industrial applications, including cutting tools, abrasives, and high-temperature structural components.

The powder is available in various grades and particle sizes to meet the specific requirements of different applications. It is typically used in the production of advanced ceramics and refractories, where its excellent mechanical properties and high-temperature resistance are critical.

Recrystallized Silicon Carbide Powder is easy to handle and process, making it an ideal choice for a range of manufacturing processes, including casting, pressing, and extrusion. Its high strength and thermal stability make it an ideal material for use in harsh and demanding environments, such as in the aerospace and automotive industries.

Overall, Recrystallized Silicon Carbide Powder is a high-quality material that offers exceptional mechanical properties and thermal stability, making it an ideal choice for use in a wide range of industrial applications.

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.
