Porous Ceramics Applications in Various Industries

Chemical Mechanical Polishing (CMP): In the semiconductor chip manufacturing process, porous ceramics can be used as polishing pad materials that effectively store and transfer polishing slurry. During the polishing process, the polishing slurry is evenly distributed over the wafer surface through the pores of the porous ceramic, ensuring uniformity in the polishing process and aiding in the precise control of wafer flatness.
Semiconductor Gas Delivery: Porous ceramics can serve as gas diffusers, delivering reactive gases uniformly into the reaction chamber. Their uniform pore structure ensures even distribution of gases within the chamber, making the deposition process more consistent.
Medical Devices: Porous ceramics have various applications in medical devices. For example, in dental implants, their good biocompatibility and bone conduction properties help integrate with surrounding tissues.
Automotive Component Manufacturing: In the manufacturing process of automotive components, porous ceramics are used to filter impurities from lubricating oil and fuel, protecting the engine and other mechanical parts.
