Sapphire Square Plate Single crystal Al₂O₃ 5.5×5.5mm Thickness 6.04 mm
The Sapphire Square Plate is a precision optical component manufactured from high-purity single-crystal aluminum oxide (Al₂O₃) through directional cutting and double-sided polishing.With dimensions of 5.5mm (size) × 6.04mm (thickness), this custom-sized plate is engineered for applications demanding stringent dimensional tolerances and superior optical performance.Leveraging sapphire’s inherent physical advantages—including exceptional hardness and high-temperature resistance—this product is widely utilized in advanced optics, semiconductors, medical devices, and precision electronics.
Sapphire Square Plate Material Properties
1. Ultra-High Hardness
Mohs hardness of 9 (second only to diamond), providing exceptional resistance to scratches and abrasion.
Suitable for high-frequency precision friction scenarios, such as sensor protective windows and optical lens covers.
2. Broad-Spectrum Optical Transmission
Transmits light across ultraviolet (200 nm) to mid-infrared (5.5 μm) wavelengths.
Achieves >90% transmittance in the visible spectrum (400–800 nm), enabling high-precision optical devices like laser windows and infrared detectors.
3. Extreme Environmental Resistance
High-Temperature Stability: Melting point of 2050°C and low thermal expansion coefficient (5.3×10⁻⁶/°C), ensuring stability from -200°C to 800°C.
Chemical Inertness: Resists acids, alkalis, and oxidation, ideal for harsh environments (e.g., oil well sensors, chemical reactors).
Electrical resistivity: >10¹⁶ Ω·cm, preventing current leakage in high-power electronics.
Sapphire Square Plate Key Applications
1. Photoelectronic Devices
LED Substrates: Sapphire Square Plate acts as a growth base for GaN-based LEDs, enhancing light extraction efficiency (>80%) for Mini LED backlights and automotive lighting.
Laser Windows: Sapphire Square Plate used in fiber lasers and medical laser systems, enduring high-energy pulses.
2. Semiconductor Packaging and Sensors
Power Device Protection: Sapphire Square Plate encapsulates IGBT and SiC MOSFETs, leveraging high thermal conductivity to reduce thermal resistance (e.g., in EV inverters).
Optical Sensors: Fabricates infrared thermometers and gas sensor windows, utilizing broad-spectrum transmission for spectral analysis.
3. Aerospace and Defense
Infrared Windows: Integrated into missile guidance systems and satellite infrared detectors, withstanding 1000°C+ surface temperatures during hypersonic flight.
Wearables: Sapphire Square Plate used in smartwatch displays and AR glasses, balancing wear resistance and transparency (6.04 mm thickness for slim designs).
Medical Endoscopes: Biocompatible surface-treated windows for high-temperature autoclave sterilization (134°C/30 min).
5. Industrial and Research
High-Temperature Probes: Sapphire Square Plate monitors boiler levels and oil well temperatures in corrosive environments (e.g., deep-sea exploration).
Quantum Device Substrates: Sapphire Square Plate supports superconducting films (e.g., MgB₂) for quantum computing and superconducting circuits.
Q1: What are the key advantages of sapphire square plates?
A1: Sapphire square plates offer ultra-high hardness (Mohs 9), broad-spectrum transparency (UV to mid-IR), and exceptional thermal stability (-200°C to 800°C), ideal for wear-resistant optics and extreme-environment electronics.
Q2: Where are sapphire square plates commonly used?
A2: They are widely applied in LED substrates (enhancing light extraction), laser windows (withstandinging high-energy pulses), and aerospace infrared detectors (resisting 1000°C+ temperatures).
