Zirconium oxide ceramic ware is a kind of widely used ceramic, because of its superior performance, it has been used more and more widely in modern society, meeting the needs of daily use and special performance. Generally, zirconia ceramic parts can be ground and polished with Al203 powder or diamond drill paste of <1 char. M micron. In addition, laser processing and ultrasonic grinding and polishing methods can also be used.
Zirconium oxide ceramic is a ceramic material with alumina as the main body, used in thick film integrated circuit. Zirconia ceramic parts have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic washing is required.
After sintering, some zirconia ceramic parts need to be refined. Products that can be used as artificial bone require a high surface finish, like a mirror, to increase lubricity.
As zirconia ceramic parts have higher hardness, it is necessary to use more hard grinding and polishing brick materials for precision processing. Usually used from coarse to fine abrasive grinding step by step, final surface polishing.
The advantages of zirconia ceramics over other enterprises:
1. High hardness, high toughness, high bending strength, and the density of zirconia ceramic parts is between 5.95-6.05 g/cm3. Among the four types of ceramic sphere materials commonly used to make ceramic materials (Si3N4, SiC, Al2O3, ZrO2), zirconia ceramic parts have the highest toughness, and over 8MPa·m1/2.
2. Zirconia ceramics have high abrasion resistance, low friction coefficient and wear resistance 15 times that of alumina ceramics. The friction coefficient is only 1/2 of alumina ceramics.
3. Zirconia ceramic parts have good insulation, corrosion resistance, no static electricity, high temperature resistance, excellent thermal insulation performance, and thermal expansion coefficient is close to that of steel.
4. Zirconia ceramic parts have self-lubricating properties. Zirconia ceramic parts can solve the pollution caused by lubricating media and the inconvenience of adding.
