High-Performance Silicon Nitride Ceramic Components: Designed For Extreme Environments And Precision Measurement
Product Introduction
This product utilizes high-performance silicon nitride (Si₃N₄) ceramic material, manufactured through advanced reaction bonding or hot
isostatic pressing processes. It is specifically developed for precision instruments, sensors, and high-temperature insulation
applications. With excellent mechanical strength, thermal shock resistance, and
chemical stability, it is an ideal material for manufacturing
precision probes, core sensor components, and high-temperature
insulating connecting rods. Its unique combination of properties
addresses the performance limitations of metals and ordinary
ceramics in high-temperature, corrosive, and precision measurement
environments.
Core Advantages
Exceptional Thermal Shock Resistance: Low thermal expansion coefficient, withstands rapid temperature changes (ΔT > 800°C) without cracking or deformation.
Ultra-High Mechanical Strength and Hardness: Flexural strength up to 800 MPa, Vickers hardness ≥1500, excellent wear resistance.
Outstanding Chemical Stability: Resists most acids and alkalis, suitable for harsh chemical environments.
Excellent Insulation Properties: High resistivity (>10¹⁴ Ω·cm), maintains good insulation characteristics even at high temperatures.
Lightweight and Biocompatible: Density only 3.2-3.3 g/cm³, with good biocompatibility.

Process Flow
Raw material preparation (high-purity Si₃N₄ powder) → Forming (dry
pressing/isostatic pressing) → Sintering (reaction bonding/gas
pressure sintering) → Precision machining (CNC grinding) →
Non-destructive testing → Dimensional inspection → Cleaning and
packaging.
Usage Instructions
Installation: Use dedicated installation tools to avoid localized stress concentration.
Environmental Adaptation: Suitable for long-term use in high-temperature and corrosive environments, but avoid contact with hydrofluoric acid.
Maintenance: Regularly inspect surface condition; use alcohol or neutral detergents for cleaning.
Precautions: Avoid impact from sharp objects; although tougher than other ceramics, it remains a brittle material.
