    Dark Gray Zirconia Ceramic Substrate: High-Precision, High-Temperature Resistant Rectangular Insulation Substrate

    Dark Gray Zirconia Ceramic Substrate: High-Precision, High-Temperature Resistant Rectangular Insulation Substrate

    Product Introduction
    This product is a dark gray rectangular substrate made from high-purity zirconia ceramic, featuring a mirror-smooth surface achieved through precision polishing and an integrally molded raised border structure along the edges. The product fully utilizes the excellent thermal stability and electrical insulation properties of zirconia material, achieving multifunctional integration through unique structural design. Its balanced mechanical properties and outstanding corrosion resistance make it an ideal choice for high-precision industrial applications.

    Core Advantages
    • Excellent high-temperature resistance: Maximum service temperature up to 1500°C with exceptional structural stability at high temperatures
    • Outstanding insulation characteristics: Volume resistivity >10¹⁵ Ω·cm, dielectric strength >15 kV/mm
    • High strength and toughness: Flexural strength ≥900 MPa, fracture toughness ≥8 MPa·m¹/²
    • Low thermal conductivity: Thermal conductivity 2-3 W/(m·K), providing effective thermal insulation
    • Superior corrosion resistance: Resistant to acids, alkalis, and oxidation, suitable for harsh industrial environments
