Application fields and uses of fused zirconia

Electrofusion zirconia has many advantages, such as high mechanical properties, chemical inertness, high-temperature stability, corrosion resistance, etc. Therefore, it is widely used in various industries and fields, and has a wide range of applications, especially as a refractory material, which is favored by many industries. The application fields of electrofusion zirconia mainly include medical products, pigments, electronic products, coatings, ceramics, etc. Its main uses include ceramic nozzles in the ceramic industry, coatings for jet engine components, production of silica glass, bridges, dental crowns, feldspar ceramic veneers, dentures, imitation diamonds, and other uses. Below, Qingdao Sailao will give you a detailed introduction.

1. High temperature wear-resistant ceramics

Continuous cast steel refractory materials, especially isobaric products. These products include discharge ports and immersion nozzles for intermediate flow channels and steel ladles. Sliding baffles also require the use of zirconia, especially for central areas exposed to higher temperatures. The mechanical strength and resistance of zirconia make it a suitable component for ceramic manufacturing. This includes ceramic knives, which are much harder than steel forks due to the high hardness coefficient of zirconia.

2. High heat resistance silica glass

Used for the production of fused alumina zirconia silica (AZS) refractory materials in the glass industry. Zirconia provides materials with excellent resistance to high temperatures and corrosion of molten glass. Due to its high heat resistance, zirconia is used as a component in crucibles, furnaces, and other high-temperature environments. In addition, zirconia improves the fire resistance of ceramics. Refractory bricks and armor plates are examples of refractory materials based on zirconia. In addition, adding zirconia to molten quartz can be used to produce silica glass, which is stronger and more stress resistant than opaque quartz glass. Zirconia can also be added to alumina for use in components of steel casting processes.

3. Insulation coating

In the ceramic industry, the production of sanitary ceramics, tableware, floor tiles, and wall tiles all require colored glaze, which can withstand high-temperature roasting processing. Zirconia is used to prepare pigments such as praseodymium yellow, vanadium blue, and iron coral powder. Diagonal zircon is also used to make ceramic pigments. Zirconia is used as a coating for jet engine components exposed to high temperatures. The low thermal conductivity and high heat resistance of this compound make it possible. Research has confirmed the effectiveness of zirconia for TBC as long as the material is applied correctly and evenly.

4. False teeth

Due to its biocompatibility, good aesthetics, and high mechanical properties, zirconia is one of the popular uses in the dental field, mainly used for bridge, crown, feldspar ceramic veneer, and dental restoration of dentures. Yttrium stabilized zirconia can also be used to produce near permanent zirconia crowns.

5. Resistance to scratches and abrasives

Due to its high mechanical stability and wear resistance, zirconia is being used as a grinding material. Due to its scratch resistance and mechanical stress resistance, this compound can also be used as a protective layer for mechanical parts.

6. Imitation diamond

Especially cubic zirconia has developed into a viable alternative to diamonds (which are very expensive). In addition to its durability and strong aesthetic similarity to diamonds, cubic zirconia also produces different cuts from diamonds and has optical defects, making it completely colorless to the naked eye. It is usually referred to as a synthetic diamond, rather than a synthetic diamond, as it visually resembles natural diamonds but does not have the same chemical properties. Examples of zirconia based jewelry include cubic zirconia rings and cubic zirconia earrings.

7. Specialized market

Special product casting, such as aerospace engines, uses zirconia as the coating for the model, which can protect the mold from thermal shock, thus being applied in precision investment casting.

8. Grinding materials

Zirconia and alumina are mixed to form coarse grinding particles, which are used for bonding and coating grinding materials on grinding wheels for grinding steel and metal alloys.

In summary, in addition to the fields and applications of the nine major industries mentioned above, fused zirconia is also used in many other industries. We will not go into detail here.
