    Insulation Performance Alumina Ceramic Bases For Precision Measurement Equipment And Industrial Inspection

    Insulation Performance Alumina Ceramic Bases For Precision Measurement Equipment And Industrial Inspection


    These alumina ceramic support bases are manufactured using 99.6% high-purity Al₂O₃ material, specifically designed for semiconductor, optical, and precision measurement equipment. Featuring ultra-high flatness of 0.01mm/m and a thermal expansion coefficient of 7.2×10⁻⁶/℃, the products maintain exceptional dimensional stability in extreme temperatures (-60℃~1500℃) and vacuum environments (≤10⁻⁸Pa).

    Core Application Fields

    • Semiconductor Equipment: Lithography wafer stages, etching reactor chamber bases

    • Precision Optics: Laser interferometer reference platforms, space telescope mirror mounts

    • Analytical Instruments: Electron microscope sample stages, mass spectrometer ion source supports

    • Industrial Inspection: CMM machine bases, roundness tester turntables

    • New Energy: Fuel cell stack supports, photovoltaic coating equipment carriers
