The main uses of zirconia are as follows:

Zirconia ceramic bearing

Zirconia full ceramic bearing has the characteristics of resistance to magnetoelectric insulation, abrasion resistance, corrosion resistance, oil-free self-lubrication, high-temperature resistance and high cold resistance, and can be used in extreme bad environment and special conditions.

At present, zirconia ceramic bearing has been adopted by the micro cooling fan, its product life and noise stability are better than the traditional ball and sliding bearing system. Foxconn has taken the lead in the use of zirconia ceramic bearings on the computer fan.

Zirconia ceramic valve

At present, the valve is widely used in every industry, and the use of metal valves has a history of more than 100 years. Although it has experienced changes in material and structure, because of the limitation of metal material itself, metal corrosion damage to the wear resistance of the valve limit, reliability, service life is equal. The effect of the mechanical and corrosion factors on the metal greatly increases the total wear and tear of the contact surface. During the operation of the valve, the surface of the friction is worn and destroyed by the results of the simultaneous mechanical action and the chemical or electrochemical interaction between the metal and the environment. For the valve, its tube is concerned. The occurrence of hydrogen sulfide, carbon dioxide and some organic acids in the medium of oil, natural gas, and oil layer water will increase the destructive force of the surface and quickly lose its working capacity.

Zirconia lapping material

Zirconia grinding ball has large hardness, small wear rate, long service life, can greatly reduce the pollution of abrasive materials, and can guarantee the quality of the products. At the same time, the density of the zirconia material is great. When the grinding medium is used as a grinding medium, the impact energy is strong, and the grinding efficiency can be greatly improved, and the grinding time can be shortened. Good chemical stability determines its corrosion resistance and can be used in acidic and alkaline media. It is widely used as grinding medium in milling, vibrating mill, planetary mill and stirred mill.

Zirconia Ceramic Cutters

Zirconia ceramic cutters have the characteristics of high strength, wear resistance, no oxidation, no rust, acid and alkali resistance, anti static, and not reacting with food. At the same time, the blade luster is like jade. It is the ideal high-tech green tool in the world. The main products in the market are: zirconia ceramic knife, scissors, razor, scalpel.

In recent years, it has become popular in Europe, America, Japan and Korea. Zirconium oxide high temperature heating material is an insulating material at normal temperature. The specific resistance is up to 1015 Omega cm, the temperature rises to 600 degrees C, and it is a good conductor at more than 1000 C. It can be used as a high temperature heating element at 1800 C, the maximum working temperature can reach 2400 degrees C, and has been successfully used for the oxidation atmosphere above 2000 centigrade. In the heating element and its equipment, the electrode materials of MHD power generation are also actively studied.
