    Silicon Nitride Ceramic U-Block - High-Temperature Resistant Structural Clamping Component

    Silicon Nitride Ceramic U-Block - High-Temperature Resistant Structural Clamping Component

    Product Overview

    This is a reaction-sintered silicon nitride ceramic U-block featuring a deep black matte finish. The U-shaped design with three precision-ground working surfaces maintains strict perpendicularity and parallelism. This specialized U-shaped structure ensures secure workpiece positioning while accommodating thermal expansion in high-temperature environments, making it an ideal clamping solution for sintering processes and precision testing applications.

    Primary Applications

    • Semiconductor Industry: Wafer sintering fixtures, diffusion process carrier blocks
    • Laboratory Settings: High-temperature furnace temperature measurement supports, vacuum environment support blocks
    • Industrial Sector: Induction heating equipment insulation supports, automated machinery guide blocks
    • Research Institutions: Material testing fixtures, specialized equipment insulation components

    Product Advantages

    → Exceptional Temperature Resistance: Continuous operation up to 1200°C
    → Superior Wear Resistance: Vickers hardness up to 1400HV
    → Ultra-Low Thermal Expansion: Coefficient of thermal expansion only 3.2×10⁻⁶/°C
    → Excellent Insulation Properties: Volume resistivity >10¹⁴Ω·cm
    → Outstanding Thermal Shock Resistance: Withstands rapid temperature changes without cracking
