Dimension: Standard or special irregular sizes customized according to requirements
Precision polished from high purity single-crystal alumina (α-Al₂O₃). It features Mohs hardness 9, melting point up to 2040℃, wide-spectrum high transmittance, strong acid and alkali resistance, excellent insulation and thermal conductivity, and superior chemical inertness. Widely applied in semiconductor optoelectronics, optical testing, laboratory high-temperature experiments, medical treatment, aerospace and precision sensors:
Laboratory Chemistry and Precision Testing
Semiconductor, LED and Microelectronics (Core Application)
Optoelectronics, Precision Optics and Sensors
Medical, Aerospace and Special Working Conditions
Core Product Advantages (Compared with Quartz, Optical Glass and Ceramic Sheets)1. Ultra-high hardness and wear resistance: Mohs hardness 9, second only to diamond, resistant to long-term friction and dust erosion with greatly extended service life for protective components.
2. Ultra-wide high temperature resistance: Melting point 2040℃, stable continuous operation at 1500℃, better thermal conductivity than quartz for superior heat dissipation and outstanding thermal shock resistance.
3. Extreme chemical inertness: Resist all strong acids, strong alkalis and hydrofluoric acid as well as plasma erosion; zero metal ion precipitation without contamination risk for high-purity manufacturing.
4. Full-spectrum high transmittance: Continuous high light transmittance from 0.15μm deep UV to 5.5μm mid-infrared, covering all UV, visible and infrared optical testing scenarios.
5. High insulation and thermal conductivity: Excellent electrical insulation for high-voltage, RF and plasma chambers; better heat conduction than quartz to stabilize heat dissipation of high-power devices.
6. Long-term dimensional stability: Nearly zero deformation under high temperature, uniform crystal structure and high polished flatness, ideal for high-precision epitaxy and optical calibration.
