    Al2O3 Ceramic Substrate Wafer Excellent Electrical Properties For Mechanical Seals

    1.0mm Thickness Aluminum Al2O3 Ceramic Substrate wafer, High Thermal Conductivity Al2O3 Ceramic plate ,4inch ceramic substrates wafer

    Al2O3 Introduce

    Alumina Ceramicis 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 generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.

    .STA High alumina ceramic wafer 99.7% Al2O3, Access to the list of our standard dimensions (Alumina and Zirconia Oxide) for electrical, vacuum or temperature resistance application.

    Basic properties of high alumina ceramic wafer.

    Polishing Service
    Our AlN substrate can be polished(single and double polish) by the advanced machine which imported
    from abroad. Ceramic substrate surface roughness can reach to 1nm without porous after being polished.
    It is perfectly suitable for the device application of small spec, high precision , wiring density and good stability.
