In industries where extreme conditions—such as high temperatures, corrosive environments, and mechanical wear—are the norm, large-diameter silicon carbide (SiC) rings have emerged as a game-changing solution. These precision-engineered components offer unmatched durability, thermal stability, and chemical resistance, making them ideal for chemical processing, semiconductor manufacturing, aerospace, and energy applications.

At AoYang, we specialize in manufacturing high-performance SiC rings with diameters ranging from 200mm to 700mm+, tailored to meet the most rigorous industrial demands.

Why Choose Large-Diameter SiC Rings?
1. Superior Thermal & Chemical Resistance

    Withstand temperatures up to 1650°C without degradation.

    Resistant to acids, alkalis, and molten metals, making them perfect for chemical reactors and furnace applications.

    Low thermal expansion ensures dimensional stability under rapid heating/cooling cycles.

2. Exceptional Wear & Corrosion Resistance

    Hardness (9.5 Mohs) exceeds most metals and ceramics, reducing wear in abrasive environments.

    Ideal for mechanical seals, bearings, and pump components where friction and erosion are challenges.

3. High Purity & Electrical Properties

    99.5%+ pure SiC for semiconductor and LED manufacturing.

    Excellent electrical conductivity for electrostatic chuck and wafer processing applications.

4. Customizable for Complex Applications

    Available in diameters from 200mm to 1000mm+ with tight tolerances (±0.02mm).

    Can be coated, grooved, or machined for specialized functions (e.g., gas distribution, plasma etching).

Key Applications of Large-Diameter SiC Rings
