High-Purity Silicon Carbide Ceramics With Superior Hardness Wear Resistance And Thermal Stability For Extreme Conditions

Black Rectangular SiC Ceramic Block with Round Hole & U-Slot

Product Introduction

This product is a high-purity Silicon Carbide (SiC) industrial ceramic component sintered using advanced manufacturing techniques. It features a simple, standardized black rectangular block design, incorporating a through round hole on one side and a precision-machined U-shaped slot on the other. This component perfectly combines the inherent superior properties of SiC material with modern industrial design, offering extreme hardness, exceptional high-temperature resistance, and excellent resistance to chemical corrosion. It is specifically engineered to meet structural, thermal, and wear-resistant challenges in demanding industrial environments.

Key Advantages

• Superior Hardness & Wear Resistance: Mohs hardness up to 9.5, second only to diamond. Its wear life is dozens of times longer than ordinary metals, significantly extending equipment maintenance cycles.

• Excellent High-Temperature Resistance: Can maintain its shape and strength in air at temperatures up to 1600°C without oxidation or softening, ensuring stable performance.

• Outstanding Corrosion Resistance: Offers excellent resistance to most acid, alkali, and salt solutions, making it suitable for highly corrosive working conditions.

• Low Thermal Expansion Coefficient: Exceptional thermal stability reduces the risk of cracking or deformation under rapid thermal cycling, ensuring dimensional stability.

• Lightweight Design: Lighter than metal parts of equivalent volume, helping to reduce the inertia of moving parts and improve equipment efficiency.

Primary Applications

This product is widely used in various precision machinery and high-end equipment, such as:

• Precision Machinery: As high-precision guide rails, sliders, bearing blocks, and connecting fixtures.

• Semiconductor Industry: For wafer sintering fixtures, conveyor rollers, and vacuum chucks.

• High-Temperature Furnace Industry: As kiln furniture, support beams, guides, and pusher plates.

• Automation Equipment: Wear-resistant connecting parts and guide components for robot end-effectors.

• Chemical Pumps & Valves: Used for seal rings, shaft sleeves, and other corrosion and wear-resistant parts.

Usage Instructions

1. Pre-Installation Check: Before installation, inspect the ceramic component for any visible cracks or chips on the surface, holes, and slots.

2. Assembly & Fixing: Utilize the round through hole for vertical fixation via a bolt. The U-shaped slot allows for horizontal sliding adjustment and locking, enabling flexible multi-directional assembly.

3. Fastening Recommendation: When assembling with metal parts, the use of elastic washers is recommended. Avoid using excessive torque when tightening to prevent local stress concentration and potential ceramic damage.

4. Environmental Compatibility: Although highly corrosion-resistant, avoid prolonged contact with hydrofluoric acid, hot concentrated phosphoric acid, and strong alkalis.

FAQ

1. Q: Can this ceramic part be customized to specific dimensions?
   A: Yes. We support non-standard customization based on customer drawings, including dimensions, hole diameters, and slot shapes.

2. Q: What are its electrical insulation properties?
   A: Silicon Carbide is an excellent electrical insulator at room temperature, though its resistivity decreases as temperature rises.

3. Q: What should be noted during assembly?
   A: The most critical point is to avoid hard impacts and point loading. Always apply force evenly and use appropriate fasteners.
