What are the different applications of Zirconia?
The exceptional mechanical properties of zirconia, its good temperature stability and favorable chemical inertness together with corrosion resistance have made this type of advanced ceramic highly suitable for use in a wide range of applications. The following are just some of the most frequent uses of this material:
Dentistry
The three most commonly used types of zirconia in dentistry are ZTA (zirconium-toughened alumina), magnesium-stabilized zirconia, and tetragonal zirconia polycrystal. The properties of these forms of zirconia allow it to serve as a material for tooth restoration due to the combination of required mechanical strength and pleasing aesthetics. The most common uses of this technical ceramic in dentistry are:
Posts: Zirconia posts prevent corrosive reactions in the patient&#;s mouth and any of the surrounding tissue, reducing pain and the potential for inflammation when compared to metal posts used prevalently until the s.
Crowns: The durability, strength, and the visual appearance of zirconia makes this the preferred material for crowns.
Abutments: The versatility in the design of zirconia with wax impressions and CAD make it the perfect material for creating custom abutments according to the exact requirements of the patient.
Ceramic brackets: These brackets serve as restraining elements for braces wires and teeth.
Implants: Finally, zirconia is an excellent material for use in dental implants due to its biocompatibility and excellent chemical stability. What&#;s more, it&#;s the preferred material for enhancing gum health because it collects less calculus and plaque.
Orthopedics
Besides dentistry, another medical application of dense zirconia involves orthopedic. Zirconia offers a wear-resistant surface with numerous mechanical benefits when compared to traditional metal alloys. Generally, ZTA is the most widely used material when it comes to zirconia and orthopedics, mainly in the following two fields:
Hip joint replacement
Knee replacement
Refractory applications
The high thermal resistance of zirconia makes it an extremely suitable choice for a wide range of refractory purposes, such as furnaces and crucibles. What&#;s more, zirconium dioxide is fireproof, making it suitable for the production of armor plates and bricks. Finally, if you add zirconia to melted quartz you get a base for the production of siloxide glass which offers better mechanical properties in comparison to quartz opaque glass.
Jewelry
Cubic zirconia represents a visual alternative to diamonds. This material produces cuts which are similar to those of a diamond and offers an optical flawlessness that&#;s completely colorless to the naked eye. However, it&#;s worth noting that cubic zirconia only offers a visual resemblance to natural diamonds without any of the required chemical and mechanical properties.
Miscellaneous
Finally, some of the other applications of zirconia advanced ceramics include:
Cutting blades
Ceramic bearings
Ceramic valves
Grinding beads
Filter plates
Many others

At present, zirconia ceramic bearings have been adopted by micro-cooling fans, and their product life and noise stability are superior to traditional ball bearing and sliding bearing system. Foxconn pioneered the use of zirconia ceramic bearings on computer cooling fans.
Zirconia ceramic valve
Due to the limitations of metal materials themselves, corrosion damage of metal has a considerable impact on the service life, reliability and wear resistance of valves. Besides, the effect of mechanical and corrosion factors on metals greatly increases the total wear on the contact surface. During valve operation, the friction surface is worn and damaged as a result of the mechanical action and chemical or electrochemical interactions between the metal and the environment. For valves, the working climate of their pipes is complex, and the hydrogen sulfide, carbon dioxide and some organic acids in the medium such as oil, natural gas, and reservoir water increases the destructive power on its surface, thus rapidly losing its working capacity.
The zirconia ceramic valve has excellent wear resistance, corrosion resistance, and high-temperature thermal shock resistance, so it is suitable for this field.
