Product variants

Sinter Grade Silicon Carbide Powder is a type of high-purity silicon carbide powder that is specifically designed for use in the sintering process. It is made from high-quality silicon carbide crystals that are crushed, milled, and screened to produce a fine powder with a consistent particle size distribution.

Sinter Grade Silicon Carbide Powder is used in the production of sintered silicon carbide components, which are used in a wide range of applications, including automotive, aerospace, and semiconductor manufacturing. Sintered silicon carbide components are known for their excellent thermal conductivity, high strength, and resistance to wear and corrosion.

During the sintering process, the sinter grade silicon carbide powder is compacted and heated to a high temperature in a furnace, where it undergoes a process of densification, which results in the formation of a high-density, fully dense silicon carbide component. The resulting sintered silicon carbide component has excellent mechanical properties, including high strength, toughness, and wear resistance.

Sinter Grade Silicon Carbide Powder is available in a range of particle sizes and purity levels to meet the specific requirements of different sintering processes. It is commonly used in the production of complex shaped components, such as seals, bearings, and wear parts.

Overall, Sinter Grade Silicon Carbide Powder is a high-quality material that is essential for the production of sintered silicon carbide components. Its unique properties make it an ideal choice for a wide range of high-performance applications, where strength, wear resistance, and thermal conductivity are critical.

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.
