With the development of zirconia ceramics, its application fields have undergone major changes. In the past, it was mainly used in refractory materials and other fields, but now it has been transformed into structural ceramics, bioceramics and electronic functional ceramics, and has become increasingly active in high-tech fields such as aerospace, aviation and nuclear industries.
1. Zirconia ceramic bearings
Zirconia all-ceramic bearings have the characteristics of wear resistance, corrosion resistance, high temperature resistance, high cold resistance, oil-free self-lubrication, anti-magnetic and electrical insulation, etc., and can be used in extremely harsh environments and special working conditions.
2. Zirconia ceramic valve
At present, the valves commonly used in various industries in my country are metal materials. Due to the limitations of the metal materials themselves, the corrosion damage of metals has a considerable impact on the duration, reliability and service life of valve wear resistance.
For valves, the climatic conditions of their pipelines are complex; the appearance of hydrogen sulfide, carbon dioxide and some organic acids in media such as oil, natural gas and reservoir water increases the destructive power of the surface, thereby rapidly losing the ability to work.
Zirconia ceramic valve has excellent wear resistance, corrosion resistance, high temperature resistance and thermal shock resistance, which can be competent in this field.
3. Zirconia grinding balls
Zirconia grinding balls have high hardness, low wear rate and long service life, which can greatly reduce the pollution of grinding raw materials and ensure product quality. Grinding dispersion efficiency.
Good chemical stability determines its corrosion resistance and can be used in acidic and alkaline media.
