High-Precision Silicon Carbide Ceramic Circular Carrier Plate (Rotary Table / Seal Ring)

High-Precision Silicon Carbide Ceramic Circular Carrier Plate (Rotary Table / Seal Ring)

Product Introduction

This product is a high-performance silicon carbide structural ceramic circular plate manufactured through advanced reaction-bonded or pressureless sintering processes. It features a distinctive silver-gray metallic luster and an extremely hard, wear-resistant surface. The design is precision-engineered with concentric rings and cross-hatched lines on the face for positioning or media distribution, along with standard mounting holes around the periphery for easy and secure installation. Combining superior mechanical, thermal, and chemical properties, this component is an ideal solution for critical applications in extreme operating conditions.

Key Advantages

• Exceptional Hardness & Wear Resistance: Mohs hardness of 9.5, second only to diamond, significantly extends service life in high-friction environments.

• Outstanding High-Temperature Resistance: Capable of long-term stable operation in temperatures up to 1650°C without softening or deforming.

• Excellent Corrosion Resistance: Highly resistant to a wide range of acids, alkalis, salts, and other corrosive media.

• High Thermal Conductivity & Low Thermal Expansion: High thermal conductivity and a low coefficient of thermal expansion result in superior thermal shock resistance, allowing it to withstand rapid temperature changes.

• Structural Stability & Lightweight: High stiffness and strength, combined with a density lower than traditional metals, contributes to equipment lightweighting.

Frequently Asked Questions (FAQ)

Q1: What are the advantages of silicon carbide ceramic over alumina ceramic?
A: Silicon carbide significantly outperforms alumina in hardness, thermal conductivity, high-temperature resistance, and strength. It is the superior choice, especially in applications requiring high thermal conductivity and thermal shock resistance.

Q2: What is the purpose of the concentric rings and lines on the surface?
A: These features are typically used for precise positioning, guiding media flow, increasing surface area, or reducing contact area to minimize friction and adhesion.

Q3: Can you customize the dimensions and hole pattern for my equipment?
A: Yes. We support custom orders based on your drawings or samples. We can adjust the diameter, thickness, hole pattern, and surface design according to your specific requirements.
