High-Strength Silicon Nitride Ceramic Block with Breakdown Voltage 20-25 KV/mm Size Range 0.5mm-100mm and Highest Melting Point 1900℃

High-Strength Silicon Nitride Ceramic Gray-Black Perforated Rectangular Block

Product Introduction

This high-performance ceramic block utilizes reaction sintered silicon nitride material, featuring a distinctive gray-black appearance with dense, uniform microstructure. Designed as a rectangular block with central circular hole, all edges are precisely chamfered with mirror-level surface finish (Ra 0.2µm). The central hole maintains exceptional coaxiality with external dimensions, featuring smooth inner walls to prevent stress concentration during operation.

Core Advantages

Exceptional Mechanical Properties: Flexural strength ≥650 MPa, hardness HRA 92-94
Outstanding Thermal Stability: Coefficient of thermal expansion 3.2×10⁻⁶/°C, operational up to 1400°C
Superior Wear Resistance: Wear coefficient below 0.5, 10x lifespan of traditional metals
Excellent Insulation: Volume resistivity >10¹⁴ Ω*cm, dielectric strength >15 kV/mm
Comprehensive Corrosion Resistance: Withstands most acids, alkalis, and salt solutions (except hydrofluoric acid)

Primary Applications

Semiconductor manufacturing: Wafer carriers, insulating fixtures, vacuum chuck components
High-temperature processing: Sintering furnace plates, heat treatment fixtures, high-temperature guides
Precision machinery: Linear guide sliders, measurement platforms, automation positioning blocks
Power electronics: High-voltage insulators, heat dissipation substrates, power module supports
Chemical equipment: Corrosion-resistant bearings, pump/valve components, reactor liners
