Ceramic liner adopt zirconia composite ceramic formula, zirconia is the role of high fracture toughness, can improve the fatigue strength of the finished product,but the pure zirconia products at 100-250 degrees Celsius under humid conditions, long-term use will appear "powder" phenomenon, The wear resistance and mechanical properties decreased, the service life of the product is limited;Alumina, its high hardness, Products have good wear resistance but fracture toughness of products are low,products are prone to cracking phenomenon.
The mixture of the two, through precise process control, realize the complementary advantages, which can overcome the zirconia "powder" phenomenon,and can overcome the disadvantage of low fracture toughness of alumina. At the same time, through a large number of experimental results obtained zirconia oxide content in about 25% or 80%,using the best.
