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.

Specification Parameters Table

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

1. Installation: Use dedicated installation tools to avoid localized stress concentration.

2. Environmental Adaptation: Suitable for long-term use in high-temperature and corrosive environments, but avoid contact with hydrofluoric acid.

3. Maintenance: Regularly inspect surface condition; use alcohol or neutral detergents for cleaning.

4. Precautions: Avoid impact from sharp objects; although tougher than other ceramics, it remains a brittle material.
