Sapphire washers are fabricated from single-crystal Al₂O₅, offering exceptional hardness, corrosion resistance, and thermal stability, making them ideal for sealing, insulation, and precision support in extreme environments.
Sapphire washers can be manufactured with larger outer and inner diameters to accommodate broader applications. Due to sapphire's inertness, they serve as excellent insulators. Moreover, the material's compressive strength enables it to withstand most operating conditions.
- Ultra-High Hardness: Mohs hardness of 9 (second only to diamond), scratch-resistant.
- Chemical Corrosion Resistance: Resistant to strong acids/alkalis (except HF).
- High-Temperature Resistance: Operational up to 1800°C (short-term).
- Low Friction Coefficient: Surface polished to Ra < 0.01 μm, minimizing wear.
- Insulation Properties: Resistivity > 10¹⁴ Ω·cm.
· Semiconductor Equipment: Insulating sealing components for wafer processing tools.
· Vacuum Systems: High-temperature sealing washers for high-vacuum chambers.
· Medical Devices: Corrosion-resistant components for surgical instruments.
· Optical Instruments: Precision support spacers and laser cavity isolators.
1. Q: Why select sapphire washers over metal/ceramic alternatives?
A: Sapphire washers provide unmatched wear resistance (Mohs 9), ultra-high temperature stability (1800°C), and perfect chemical inertness (HF except).
2. Q: What industries require sapphire sealing washers?
A: Critical applications in semiconductor processing (CMP), ultra-high vacuum chambers, implantable medical devices, and precision laser systems.
