Zirconia-Toughened Alumina (ZTA) wear-resistant ceramics are composed of alumina and zirconia, combining the high hardness of alumina with the high toughness of zirconia. Through microcrystalline strengthening and dispersion toughening mechanisms, the material significantly improves impact resistance while maintaining excellent wear performance. ZTA ceramics achieve a Rockwell hardness of HRA 90 or above and a wear volume of less than 0.01 cm³, maintaining stable abrasion resistance under demanding conditions such as high speed and high pressure.
The mining, mineral processing and bulk materials handling industries face severe abrasive wear and impact loads from ore particles on processing equipment. Critical components including chutes, hoppers, transfer points, cyclones and pipe elbows demand wear lining materials with both high abrasion resistance and impact resistance. ZTA ceramic liners have demonstrated service life 2.8 to 4 times longer than conventional alumina ceramic liners under these operating conditions. The material is also chemically inert against most acids, alkalis and high-temperature environments, with service capability up to 1500°C.
ZTA wear-resistant ceramics provide a balanced solution between pure alumina and pure zirconia ceramics, delivering both performance and cost efficiency. Modular liner panels support flexible installation via high-strength adhesive or rubber composite vulcanization, and only damaged tiles need replacement for maintenance. Pingxiang Chemshun Ceramics Co., Ltd, established in 2002, is a professional manufacturer and exporter of wear-resistant ceramics with an annual output of 5,000 tonnes, of which approximately 60% is directly exported to overseas markets. The company’s core products include ZTA ceramic liners, ZTA rubber-ceramic composite liners and ceramic-lined pipes, widely applied in mining, mineral processing, power generation, steel, cement and petrochemical industries.
