    High Purity Alumina Ceramic Seal Rings for Semiconductor or Vehicles

     

     

    In the semiconductor industry, high purity semiconductor alumina ceramic ring  ceramic components must be high purity to withstand harsh plasma etch environments. High purity alumina ceramic rings  is required not only for its inert properties, but for its ability to be fabricated in a wide variety of complex shapes, up to 30” in diameter.

    Industrial uses of structural technical ceramics continues to grow. Modern Ceramics fabricates structural ceramic components for a variety of industrial applications. A few examples are listed below:

    • Alumina ceramic Semiconductor rings, lift pins, and end effectors
    • Ceramic Precision medical and laser instrumentation components for wear resistance and electrical isolation
    • Ceramic Bushings, punches, dies, and forming tools
    • ceramic Fluid handling components such as pump plungers, liners, tubes, shafts, pistons and cylinders
    • Ceramic Mechanical seals, ceramic valve seats, and ceramic control valve components
    • ceramic Thread guides, ceramic screws, ceramic spray nozzles
    • ceramic Industrial knives and blades

    Ceramics rings have a high hardness and are often used for abrasion resistance in a multitude of industrial applications. However, hardness is not the only factor to consider. In a high friction environment, a ceramic material with a low thermal conductivity will allow the surface to remain hot. From a tribological standpoint, hot surfaces wear faster than cool surfaces regardless of a materials hardness.

     

    Made from high-tech Al2O3 Alumina Ceramic rings. Alumina ceramic rings  is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.

    Alumina ceramic is the material of choice for alumina wear parts. The proven wear and heat resistance of alumina wear parts makes them ideal for the manufacture of wear-resistant components.

    Alumina has a high melting point, high hardness, although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced.

    Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.

    Good chemical stability of alumina leads to high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Testing has shown that the low chemical solubility of alumina ceramics components makes them highly resistant to chemical corrosion. This is what makes high purity alumina the material of choice for components in a wide range of industrial applications.

    Adventage:

    1. High purity, we have 95% Al2O3 plate with density 3.6g/cm3 and 99.7% Al2O3 plate with density 3.9g/cm3

    2. Tight tolerance, all the plate can be machined to tight tolerance +/-0.02mm at most, surface roughness can reach to Ra0.2um at most.

    3. Inspection: each single plate will be checked before shipping.

    4. Low transportation cost. We have long time cooperated shipping agency, which can provide very low prices.

     

     

     

    Applications:
    •  Alumina plates are hard enough to become armor for personnel or vehicles.
    •  The corrosion resistivity of alumina plates makes them a great material for chemical industry.
    •  Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
    •  Used for making parts for CVD, ion implants, photolithography, and semiconductor parts.
    •  In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles and insulators.
