Product Specification

Rectangular Silicon Carbide Ceramic Structural Block (with Central Through Hole)

Product Introduction

This product is a rectangular silicon carbide (SiC) ceramic structural block manufactured using pressureless sintering technology. Silicon Carbide (SiC), as a representative of advanced engineering ceramics, possesses excellent high-temperature stability, outstanding mechanical strength, and remarkable wear resistance. The product features a standard rectangular design with a precision central through hole at the top, offering a simple and symmetrical structure. The surface is precision ground to a mirror-like finish. The deep black appearance demonstrates its exceptional physical and chemical properties, making it an ideal choice for harsh working conditions involving high temperatures and severe wear.

Primary Applications

• High-Temperature Equipment Structural Components: Widely used in semiconductor manufacturing equipment, vacuum furnace support beams, insulating pillars, etc.

• Precision Machinery Guide Parts: Serves as wear-resistant sliders for linear guides, positioning reference blocks for precision measuring equipment.

• Chemical Industry Wear-Resistant Components: Suitable for key components like wear-resistant bushings and mechanical seal rings in chemical pumps and valves.

• Automation Equipment Accessories: Used as wear-resistant structural blocks in robot end-effectors and automated conveying systems.

Product Advantages

• Exceptional Wear Resistance: Hardness up to HRA 93, wear resistance is more than 20 times that of high-chromium cast iron.

• Excellent High-Temperature Stability: Maintains excellent mechanical properties even in high-temperature environments up to 1650°C.

• Outstanding Thermal Shock Resistance: Can withstand rapid heating and cooling thermal shocks without cracking.

• Superior Chemical Inertia: Excellent resistance to acid and alkali corrosion, suitable for various corrosive environments.

• High Stiffness and Lightweight: Density is only 3.12 g/cm³, 60% lighter than steel with comparable stiffness.
