Insulating U-Groove Silicon Carbide Ceramic Component For Semiconductor Equipment And Devices In Corrosive Environments
U-Groove Silicon Carbide Ceramic Structural Component
Product Introduction
This product is a U-groove silicon carbide (SiC) ceramic structural component manufactured using hot-press sintering technology. Silicon Carbide (SiC), representing the third generation of engineering ceramics, possesses exceptional mechanical properties and thermal stability. The product features a unique U-shaped block design with a precision groove on the top and a central circular hole at the bottom, embodying a perfect combination of functionality and structural integrity. Its dark gray surface undergoes precision grinding, ensuring accurate dimensions and easy installation. It is specifically developed for harsh industrial environments involving high temperatures and severe wear.
