Environmentally Friendly Silicon Nitride Ceramics Are Non-Toxic And Non

Product Specification

Environmentally Friendly Silicon nitride ceramics are non-toxic and non-polluting making them a sustainable and environmentally friendly material

Introduction
Silicon nitride ceramic wear-resistant sliding sheets and gaskets are special engineering ceramic components made from high-purity silicon nitride (Si₃N₄) material through advanced sintering processes. This material combines exceptional wear resistance, extremely low friction coefficient, outstanding self-lubricating properties, and remarkable mechanical strength, specifically designed to withstand extreme wear conditions. Its performance far exceeds that of traditional metal and ordinary ceramic materials, maintaining long-term stable service life in harsh environments such as high speed, high temperature, and strong corrosion, significantly reducing equipment maintenance costs and downtime.

Applications
This product is widely used in industrial fields with severe wear and special working conditions:

• Petrochemical Industry: Centrifugal pump mechanical seal rings, compressor sliding sheets, valve sealing surfaces

• Automotive Industry: Turbocharger rotors, engine bearings, fuel injection system components

• Smart Manufacturing: Industrial robot bearings, precision guide sliders, automation equipment wear-resistant parts

• Energy and Power: Gas turbine sealing components, wind turbine generator wear-resistant parts

• High-End Equipment: Aerospace engine components, precision instrument wear-resistant elements

Advantages

1. Exceptional Wear Resistance: Vickers hardness up to 1600HV, wear resistance is more than 10 times that of high-quality alloy steel

2. Self-Lubricating Properties: Extremely low friction coefficient (0.1-0.3), can operate normally under oil-free or low-oil conditions

3. High Temperature Resistance: Can maintain stable performance in high temperature environments up to 1200°C, with excellent thermal shock resistance

4. Corrosion Resistance: Excellent corrosion resistance to most acid and alkali media

5. Lightweight Design: Density only 3.2g/cm³, 60% lighter than steel, significantly reducing moving part inertia

FAQ
Q1: What are the advantages of silicon nitride ceramic sliding sheets compared to metal sliding sheets?
A1: Longer service life (3-5 times), higher operating temperature, better corrosion resistance, and no need for lubrication systems, resulting in lower maintenance costs.

Q2: Can products be customized according to special working conditions?
A2: Support complete customized production, can provide personalized solutions including material formula optimization and structural design improvements according to usage conditions.

Q3: How to determine if a product needs replacement?
A3: Recommend judging through regular wear measurement and observing operational parameter changes. Replacement is recommended when thickness wear exceeds 10% of original size or performance degradation occurs.
