Ceramic materials have good hydrophilic properties, which can greatly increase the effective specific surface area of ​​the packing. The corrosion resistance of ceramics is also good, thus expanding the scope of use. As early as the 1960s, my country began to develop ceramic plate corrugated packing and achieved initial industrial application. Since the 1980s, my country's scientific research units, colleges and universities, design units and ceramic packing manufacturers have jointly formed a technical team for joint research and cooperative development, and have effectively developed a variety of ceramic plate corrugated packing. In 1986, SK thin-walled ceramic corrugated packing was developed; in 1988, TCP-1 ceramic corrugated packing was developed. Because ceramic packing is fragile, the increase of packing fragments in the tower in the later period of use will increase the pressure drop of the packing, reduce the flux, and reduce the efficiency. Therefore, increasing the strength of the packing and reducing the weight have become the key to expanding the application range of ceramic packing. In the late 1980s, by changing the clay composition, the above technical problems have been initially solved. High-strength and lightweight ceramic plate corrugated packing that can meet industrial requirements has been developed in China and achieved results.

Sulzer Company developed a ceramic plate corrugated packing named Kerapak between 1976 and 1977. Its structure is similar to that of BX type (500X type) wire mesh corrugated packing. Sumitomo Corporation of Japan also sells this packing. In 1988, it launched Melladur ceramic plate corrugated packing. Its geometric structure is similar to that of Mellapak perforated plate corrugated packing and has high flow performance.

SK type ceramic packing is made of hard porcelain, the main components of which are clay, quartz, feldspar, etc., and is specially fired. Kerapak packing is made of aluminum-silicate ceramic, with thinner walls and greater mechanical strength. Ceramic packing is made into a whole disc shape when the diameter is less than 400mm or 450mm, six pieces are made into a spliced ​​shape when the diameter is less than 800mm, and nine or more pieces are made into a spliced ​​shape when the diameter is more than 800mm. Since the packing is not elastic, the packing diameter must be a few millimeters smaller than the inner diameter of the tower. The gap between the packing and the tower wall can be filled with glass fiber, asbestos or polytetrafluoroethylene tape to prevent wall flow and wear between the packing and the tower wall.
