Product name : zirconia ceramics
Specification : zirconia ceramic parts ( HY-TCG )
Introduction of zirconia ceramics :
As the most important material in advanced ceramics, zirconia ceramic material is a very important basic material for the development of modern high-tech industry. Zirconia ( ZrO2 ) is a metal oxide with high melting point. Its relative molecular weight is 123.22, boiling point is 4300 °C, softening point is in the range of 2390 °C -2500 °C, and melting point is 2715 °C. Zirconia is insoluble in water, sulfuric acid, hydrochloric acid and nitric acid, and slightly soluble in hydrofluoric acid and concentrated sulfuric acid when heated. Pure zirconia is white, and pure zirconia is pale yellow. Zirconia ceramics have high hardness, high wear resistance, good high temperature thermal stability and thermal shock resistance. With the development of zirconia ceramics, its application field has expanded from the field of refractory materials in the past to the field of structural ceramics, bioceramics and electronic functional ceramics. It also has active applications in high-tech fields such as aerospace and nuclear industry.
Application of zirconia ceramics in structural ceramics :
① Ceramic bearings
Zirconia all-ceramic bearings have the characteristics of wear resistance, corrosion resistance, high temperature resistance, high cold resistance, oil-free self-lubricating, anti-magnetic and electrical insulation, and can be used in extremely harsh environments and special working conditions. At present, zirconia ceramic bearings have been adopted by micro cooling fans, and their product life and noise stability are better than traditional ball and sliding bearing systems.
② Ceramic valve
Due to the limitation of the metal material itself, the corrosion damage of the metal has a considerable impact on the duration, reliability and service life of the valve wear resistance. Zirconia ceramic valves have excellent wear resistance, corrosion resistance, high temperature resistance and thermal shock resistance. They can effectively replace traditional metal alloy valves, especially in harsh working environments, effectively reduce wear and improve corrosion resistance, thus greatly improving life.
