In the past, zirconia ceramics were mainly used as refractory materials, but with the development of electronics and new material industries, zirconia ceramics have been more and more widely used in electronic ceramics, structural ceramics and functional ceramics. At present, Japan is a world leader in the manufacture of zirconia raw material powder, as well as in the manufacture of electronic ceramics and structural ceramics.
Because zirconia has the characteristics of high strength, high toughness and corrosion resistance, the compressive strength can reach 2100MPa at normal temperature, which can be used to manufacture jet engines, internal combustion engines, non-lubricated ball bearings and steam turbines of space vehicles; zirconia has non-magnetic, The excellent properties of non-conductivity and wear resistance can be used to manufacture medical instruments and cutting tools; zirconia has high hardness and excellent wear resistance, and is widely used in the production of cold forming tools, cutting tools, grinding and grinding components, etc.
In electronic ceramics, zirconia is mainly used in the manufacture of voltage components, filters, ultrasonic oscillators, etc. As a functional ceramic, zirconia is mainly used in the manufacture of gas sensors, temperature sensors and sound sensors. In addition, zirconia is also being widely used in thermal barrier coatings, refractories, textiles and other fields. With the rapid development of new materials and the electronics industry, zirconia will be more used in structural ceramics, functional ceramics and electronic ceramics, and the demand will increase.
