    Insulating Spacers For Scientific Instruments 99.6% Al₂O₃ Material Ra Lt 0.1 Mu M Surface Roughness 320M

    Insulating Spacers For Scientific Instruments 99.6% Al₂O₃ Material Ra Lt 0.1 Mu M Surface Roughness 320M


    This series of alumina ceramic insulating spacers are manufactured from 99.6% high-purity Al₂O₃ material, featuring ultra-high volume resistivity (>10¹⁵Ω·cm) and dielectric strength (25kV/mm). With specialized surface treatment achieving Ra<0.1μm surface roughness, these components are specifically designed for electrical isolation requirements in high-voltage equipment, precision instruments, and semiconductor manufacturing devices.

    Core Applications

    • Power Electronics: IGBT module isolation, high-voltage power component insulation

    • Semiconductor Equipment: Etcher RF matcher isolation, PECVD equipment insulating rings

    • Medical Devices: MRI equipment insulation components, HF surgical instrument isolation

    • Scientific Instruments: Particle accelerator insulating rings, high-energy physics experimental setups

    • Industrial Automation: Servo motor insulating washers, robotic joint isolation

    Performance Advantages

    Superior Insulation: Withstands up to AC 30kV (1mm thickness)
    High-Temperature Resistance: Continuous operation from -60℃ to 1200℃
    Precision Dimensions: ID/OD tolerance ±0.01mm
    Aging Resistance: <5% insulation degradation over 10 years
    Multifunctional: Optional conductive/insulative zone design

    Installation Guidelines

    Mounting Notes:

    • Clean contact surfaces with alcohol before installation

    • Recommended torque: M3 bolts 0.5N·m, M6 bolts 2.5N·m

    • Avoid direct rigid connection with materials of different CTE

    • Silver plating recommended for high-frequency applications

    Maintenance Requirements:

    • Check insulation resistance every 5,000 hours

    • Replace immediately if surface carbonization is observed

    • Storage humidity should be <60%RH

    Service Commitment
