Product Description Product Description Sapphire substrate is a thin slice processed from single-crystal sapphire material. Due to its outstanding physical and chemical properties, this material is widely used in optoelectronics, microelectronics, and other high-tech fields. Sapphire substrates possess high transparency, excellent thermal conductivity, and chemical stability, making them a key material in many advanced technologies.Product Features Optical Properties: Sapphire exhibits high transparency and a stable refractive index across the ultraviolet to near-infrared spectrum. This makes sapphire substrates widely applicable in optical devices such as high-precision lenses and filters.Thermal Properties: Sapphire has high thermal conductivity, effectively dissipating heat, and a low coefficient of thermal expansion, enabling it to maintain stable dimensions and shape under high-temperature conditions. Consequently, sapphire substrates play a crucial role in high-power electronic devices.Mechanical Properties: Sapphire is renowned for its extreme hardness and bending strength, enabling it to resist wear and mechanical stress. This characteristic makes it outstanding in harsh working environments, particularly in applications requiring high durability, such as watch faces and protective windows for high-precision instruments.Chemical Corrosion Resistance: Sapphire demonstrates excellent resistance to most acids, alkalis, and solvents, maintaining stability in harsh chemical environments. This makes sapphire substrates widely applicable in chemical experiments and industrial production.Chemical Stability: Sapphire possesses extremely high chemical stability, retaining its physical and chemical properties unchanged even under high-temperature and strong radiation conditions. This makes it an ideal material for many high-tech applications.Product Applications LEDs (Light Emitting Diodes): Sapphire substrates are the primary material for manufacturing high-brightness LEDs. Their excellent thermal conductivity and stable optical properties enable LEDs to maintain superior performance under high-temperature and high-brightness operating conditions.Laser Diodes: Sapphire's high optical transparency and stability make it an ideal base material for laser diodes, ensuring efficient and stable light output from the lasers.High-Power Electronic Devices: Sapphire's excellent thermal conductivity effectively dissipates heat, ensuring the stability of high-power electronic devices under high-temperature conditions. Additionally, its mechanical strength and chemical stability provide reliable structural support for these devices.Product Parameters Material:Single-crystal (99.999%)Orientation: C-plane (0001) offset from M-axis by 0.2°±0.1°Diameter:200.00±0.2mmThickness1300±25μm, 750±25μm, or 1000±25μmPrimary Side Flat:57.5±2.5mmOF Orientation FlatA-axis ±0.1°Front Surface Roughness:Ra<0.2nmBack Surface Roughness:0.8~1.2μm (or double-sided polished, both sides Ra<0.3nm)TTV (Total Thickness Variation):<20umBow:-30~0umWarp:<20umPackaging:Vacuum-sealed container, filled with nitrogen in a Class 100 environment
