Alumina Ceramic Insulation Supports For Semiconductor Manufacturing Equipment And Vacuum Coating Chambers

Alumina Ceramic Insulation Supports For Semiconductor Manufacturing Equipment And Vacuum Coating Chambers

Product Introduction

The alumina ceramic insulating support ring is manufactured from high-purity (above 99%) alumina material, featuring exceptional electrical insulation properties, mechanical strength, and high-temperature resistance. This product maintains stable physical and chemical performance even in high-temperature, high-pressure, and corrosive environments, widely used for insulation support and positioning in power electronics, vacuum equipment, and other fields.

Primary Applications

• Electrical Equipment: High-voltage switches, insulators, circuit breakers

• Electronics Industry: Semiconductor manufacturing equipment, vacuum coating chambers

• New Energy: Fuel cell stacks, electrolyzer insulation components

• Vacuum Technology: High-vacuum system insulation supports

• High-Temperature Equipment: Kiln, heating device insulation structures

Key Advantages

✅ Ultra-High Insulation: Volume resistivity >10¹⁴Ω·cm (room temperature)
✅ High-Temperature Resistance: Continuous operating temperature up to 1600°C
✅ High Mechanical Strength: Compressive strength >2000MPa
✅ Precision Dimensions: Tolerance up to ±0.01mm
✅ Corrosion Resistance: Resists acid/alkali erosion (except hydrofluoric acid)
