    Sapphire (Al₂O₃) C-Plane Wafers, Small Diameter (Dia. 3 mm – 1″)

    Overview: High-purity single-crystal sapphire (Al₂O₃) wafers, C-plane (0001) orientation, in small diameters from Dia. 3 mm up to 1 inch. Available in single-side polished (SSP) and double-side polished (DSP) options. These substrates deliver exceptional hardness, optical transparency (UV to IR), thermal stability, and chemical inertness, making them ideal for a wide range of research applications.

    Key Specifications:
    – Orientation: C-plane (0001)
    – Diameter: Dia. 3 mm to Dia. 25.4 mm (1 inch)
    – Thickness: 0.5 mm – 3.0 mm (varies by diameter)
    – Polish: SSP (single-side polished) or DSP (double-side polished)
    – Purity: 99.999%+ single-crystal Al₂O₃
    – Crystal Grade: Optical/research grade
    – Surface Roughness: <0.5 nm Ra (polished face)

    Material Properties:
    – Hardness: 9 Mohs (second hardest natural material)
    – Melting Point: 2,040°C
    – Optical Transmission: 0.15 – 5.5 μm (UV to mid-IR)
    – Thermal Conductivity: ~46 W/(m·K) at RT
    – Dielectric Constant: ~9.3 – 11.5

    Applications:
    – Optical windows and viewport substrates (UV, visible, IR)
    – Thin-film oxide research (ZnO, NiO, TiO₂ on sapphire)
    – Power electronics and semiconductor device research
    – High-temperature substrate for CVD and PVD processes
    – Substrate for GaN and other III-nitride research
    – Ultrahard substrate for wear-resistant coatings
