Industrial-Grade SiC Structural Ceramic Block With Rounded Edges For Safe Handling And Stress Concentration Prevention

Dark Gray Matte Rectangular SiC Ceramic Block with Center Through-Hole

Product Introduction

This product is a high-performance silicon carbide (SiC) structural ceramic manufactured through high-temperature sintering. It features a standardized rectangular block design with a deep, matte gray surface that offers a fine texture and an industrial-grade aesthetic. The design prioritizes practicality and safety, with all edges meticulously rounded to prevent stress concentration and ensure safe handling. The central through-hole facilitates easy installation and secure fastening. Combining exceptional high-temperature resistance, extreme hardness, and stable chemical inertness, this component is an ideal solution for demanding applications in extreme environments.

Key Advantages

• Superior Hardness & Wear Resistance: Approaches diamond-like hardness, offering wear resistance far superior to traditional metals, resulting in a dramatically extended service life and reduced maintenance costs.

• Excellent High-Temperature Stability: Maintains structural integrity and performance in oxidizing atmospheres up to 1600°C, with no softening or deformation.

• Outstanding Thermal Shock Resistance: The combination of a low thermal expansion coefficient and high thermal conductivity allows it to withstand severe thermal cycling without cracking.

• Stable Chemical Inertia: Demonstrates excellent resistance to most acids, alkalis, and other corrosive media, suitable for complex chemical environments.

• Robust & Lightweight: High density provides high structural strength, while being lighter than heavy metal alloys, contributing to equipment weight reduction.

Primary Applications

This block is widely used in industrial sectors requiring high reliability, wear resistance, and temperature tolerance, such as:

• Precision Machinery & Automation: As high-precision guide rails, wear-resistant sliders, bearing blocks, and robotic arm connectors.

• Semiconductor Manufacturing Equipment: For wafer sintering fixtures, conveyor rollers, and fixing components in vacuum environments.

• High-Temperature Industrial Furnaces: As load-bearing beams, setters, and pusher plates within kilns.

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

• R&D & Experimental Setups: As fixtures for high-temperature reactions and precision positioning blocks.

Usage Instructions

1. Pre-Installation Check: Before installation, inspect the ceramic block to ensure it is free from cracks or chips, particularly around the hole edges.

2. Assembly & Fixing: Fasten to metal components using a bolt through the center hole. It is recommended to use elastic washers (e.g., copper, spring washers) at the ceramic-metal interface to buffer stress.

3. Torque Control: Use a torque wrench during fastening to avoid excessive force that could cause crushing or cracking of the ceramic hole wall.

4. Environmental Note: Avoid direct and prolonged contact with highly corrosive agents such as hydrofluoric acid and hot concentrated alkalis.

After-Sales Service

We offer a 12-month product warranty. Within this period, any failure confirmed to be caused by material or manufacturing defects will be repaired or replaced free of charge. Professional technical consultation is also available.

FAQ

1. Q: Are the rounded edges a standard feature of this block?
   A: Yes, all edges are rounded as a standard finish to protect the component and ensure safe handling.

2. Q: Can it be used in the same assembly with alumina ceramic parts?
   A: Yes, but it is crucial to account for their different thermal expansion coefficients in the design to avoid generating excessive stress at high temperatures.

3. Q: What is the typical surface roughness (Ra)?
   A: The standard finish is a ground matte surface with an Ra value typically below 0.4μm. A polished finish for lower roughness can be customized upon request.
