Silicon Nitride Ceramics Stable And Durable Components For High-Precision Equipment And Measuring Instruments

Silicon Nitride Ceramics Stable And Durable Components For High-Precision Equipment And Measuring Instruments

 

Introduction
Silicon nitride ceramic precision components are high-performance ceramic assemblies specifically designed for optical equipment, measuring instruments, and automated machinery. Manufactured from high-purity silicon nitride (Si₃N₄) material through precision manufacturing processes, they exhibit exceptional mechanical properties, excellent thermal stability, and outstanding dimensional stability. These components play crucial roles in precise positioning, reliable connection, and stable load-bearing within equipment, ensuring maintained high precision and stability during long-term use.

Applications
Widely used in positioning, connecting, and load-bearing components of high-precision equipment:

  • Optical Equipment: Optical platform supports, lens mounting brackets, laser positioning bases

  • Measuring Instruments: CMM guideway supports, precision sensor mounting seats

  • Automated Machinery: Industrial robot joint bearing seats, precision transmission mechanism connectors

  • Semiconductor Equipment: Lithography machine positioning platforms, wafer handling robot arm connectors

  • Precision Instruments: Astronomical telescope mounts, microscope focusing mechanisms

Advantages

  1. Exceptional Dimensional Stability: Thermal expansion coefficient only 3.2×10⁻⁶/℃, ensuring long-term usage precision

  2. Excellent Mechanical Properties: Flexural strength ≥800MPa, hardness ≥1650HV

  3. Outstanding Thermal Stability: Maintains stable performance within -60℃ to 1200℃ temperature range

  4. Low Density and High Stiffness: Density 3.2g/cm³, 60% lighter than steel with high rigidity

  5. Superior Corrosion Resistance: Resistant to acids and alkalis, suitable for various working environments
