High Precision Precise Dimensions Smooth Surface And Excellent Flatness Ensuring High-Precision Equipment Performance
Introduction
Silicon nitride ceramic support columns are high-performance
structural ceramic components manufactured from high-purity silicon
nitride (Si₃N₄) material through advanced sintering processes. This
product perfectly combines the excellent mechanical properties,
superior thermal stability, and outstanding corrosion resistance of
silicon nitride ceramic, featuring extremely high mechanical
strength, very low thermal expansion coefficient, and excellent
wear resistance. Specifically designed for high-precision
equipment, it provides stable structural support, reliable
dimensional stability, and long service life, making it an ideal
choice for precision equipment manufacturing.
Applications
Widely used in various high-precision, high-demand support
application scenarios:
Semiconductor Equipment: Lithography machine support columns, etching machine load-bearing columns
Precision Measurement: CMM machine pillars, laser measuring instrument supports
High-Temperature Equipment: Heat treatment furnace supports, sintering furnace load-bearing columns
Medical Equipment: Medical imaging equipment brackets, surgical robot supports
Scientific Instruments: Electron microscope sample stage supports, precision laboratory equipment brackets
Advantages
Ultra-High Mechanical Strength: Compressive strength ≥2000MPa, excellent load-bearing capacity
Excellent Thermal Stability: Thermal expansion coefficient only 3.2×10⁻⁶/℃, excellent dimensional stability
Exceptional Wear Resistance: Vickers hardness ≥1650HV, long service life
High-Temperature Resistance: Can work stably for long periods in high temperature environments up to 1200℃
Chemical Stability: Acid and alkali corrosion resistant, suitable for harsh environments
