Therefore, the characteristics of wear-resistant ceramics of Jing Cheng Hua porcelain are as follows:1. high hardness, excellent wear resistanceAlumina ceramic adopts 95%AL2O3 to add a variety of wear-resistant materials of the unique formula, alumina 95%, Cr2O31.5%, TiO20.3%, SiO21.8%, Fe2O30.2%, Na2O0.2%, rare earth 1%. 100 tons dry pressing forming, with large density, high toughness, wear resistance and so on. Tested by Shanghai Institute of ceramics, CAS, the abrasion resistance of the wear-resistant ceramics produced by Jing Hua porcelain is 266 times of that of manganese steel and 171.5 times of that of high chromium cast iron.2. strong toughness (excellent impact resistance)The company is generally not up to Hunan City, wear-resistant ceramic fine production company introduced very similar to Al2O3 and the lattice of Cr2O3 and TiO2 in the formula, at the same time added from Japan Toshiba Co introduced the ZnO whisker in the sintering process to form solid solution with Al2O3, the grain refinement, promote sintering and improve fracture toughness of role. Fracture toughness of alumina reached KIC more than 4.8Mpa.m1/2, the fracture toughness of KIC is larger than 7.5Mpa.m1/2, zirconia ceramics and ceramic increased under the rubber layer with good elasticity, on the impact of oversize material has good buffer capacity.
