Application of Zirconia Ceramics

Following the development trend of zirconia ceramics, its main use has already undergone major changes. In the past, the key was to be used in industries such as refractory and thermal insulation materials. At present, it has long been transformed into industries such as structural ceramics, bioceramics and ceramics for electronic devices, and is gradually active in high-tech industries such as aerospace, airlines and nuclear industries.

a. Refractory insulation materials

Zirconia has stable physical properties, excellent heat resistance and high temperature damage resistance, so it can be used as high temperature porcelain coating and high temperature fireproof material crafts. It can also be added to other refractory insulation materials to improve flame retardancy. The refractory insulation materials of zirconia material include: zirconia die water part, zirconia crucible, zirconia refractory fiber, zirconium corundum brick and its hollow zirconia ball refractory insulation materials, etc. This kind of raw material is mainly used in the metallurgical industry and aluminum silicon In the manufacturing industry such as acid salt.

b. Structural ceramics

Zirconia ceramics have good physical properties, and they are widely used as construction materials for engineering projects. Zirconia ceramic rolling bearings have higher service life reliability than traditional drag and roller bearings, and are more wear-resistant and corrosion-resistant; zirconia ceramics can be made into diesel engine cylinder linings, piston rings and other parts, reducing quality The zirconia ceramic gate valve can reasonably replace the traditional metal material aluminum alloy gate valve, especially in the extreme office environment, reasonably reducing damage and improving corrosion resistance, thereby further improving the service life; zirconia Ceramics can be used to make ceramic knives, which are sharper than traditional steel knives, and are exquisite and beautiful in appearance.

c, role porcelain

Zirconia has electrical conductivity at high temperatures, especially after adding thickeners, the electrical conductivity can be stronger, coupled with the high strength and ductility of zirconia ceramics, can be made into zirconia solid fuel rechargeable batteries. In addition, piezoelectric materials produced from the key component of zirconia have long been widely used. Oxygen sensors made of zirconia are highly sensitive, and have been used to test the oxygen content of molten steel, the proportion of CO2 and natural gas in diesel engines, and the oxygen content of organic waste gas. Zirconia ceramic raw materials can also be made into intelligent automatic detection system software for temperature, sound, working pressure and acceleration sensors.

d. Medical biotechnology

The most common use of zirconia ceramic raw materials in the biomedical industry is as raw materials for dental repair and numerical control blades for surgical treatment; in countries such as Japan and the United Kingdom, the ceramic teeth made of zirconia materials have good clarity and good compatibility. High quality; and at this stage, some scientific researchers have already succeeded in using zirconia raw materials to make synthetic bones for diagnosis and treatment purposes.
