Product Introduction
The silicon carbide ceramic rectangular bar is an industrial ceramic component manufactured through reaction bonding or pressureless sintering processes. It features a standard rectangular structure with precision circular through-holes at both ends and a smooth, dense dark gray surface achieved through precision grinding. Made from high-purity silicon carbide raw materials using advanced ceramic manufacturing techniques, it exhibits uniform microstructure and excellent physical and chemical properties, making it an ideal replacement for traditional metal materials.
Main Applications
Precision machinery guides and slides
High-temperature kiln rollers and load-bearing beams
Semiconductor process fixtures and carriers
Chemical pump valve sealing components
Laser equipment support structures
Photovoltaic industry transmission guides
Product Advantages
Extreme hardness: Mohs hardness reaches 9.2, second only to diamond
