Product Description

Alumina Ceramic Insulation Seals: Ideal Choice for High-Performance Industrial Applications

Introduction
Alumina ceramic insulation seals are specialized ceramic components manufactured from high-purity alumina (Al₂O₃) material through precision molding and high-temperature sintering processes. This product combines excellent electrical insulation properties with reliable airtightness, maintaining stable performance in high-temperature, high-pressure, and corrosive environments, making it an indispensable key component in high-end industrial equipment.

Applications

  • Electronics and Electrical: Vacuum relay seals, high-voltage switch insulators, semiconductor equipment sealing rings

  • Energy and Power: Fuel cell sealing gaskets, solar equipment insulation components, nuclear power equipment sealing assemblies

  • Aerospace: Avionics sealing, spacecraft insulation components, propulsion system seals

  • Research Equipment: Vacuum chamber sealing flanges, experimental equipment insulation parts, analytical instrument sealing assemblies

Advantages

  1. Excellent Insulation Performance: Dielectric strength ≥20kV/mm, volume resistivity >10¹⁵Ω·cm

  2. Superior Sealing Performance: Leak rate <1×10⁻¹⁰Pa·m³/s

  3. High Temperature Resistance: Long-term service temperature up to 1600℃

  4. Corrosion Resistance: Resistant to acid and alkali corrosion, excellent chemical stability

  5. High Mechanical Strength: Compressive strength ≥2800MPa, flexural strength ≥380MPa
