Zirconium dioxide, with the chemical formula ZrO2, is the main oxide of zirconium. It is usually white, odorless and tasteless crystals and is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. It is chemically inactive and has the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient, making it an important high-temperature resistant material, ceramic insulating material and ceramic light-shielding agent, and also the main raw material for artificial drills.

PRODUCT USES

SYNTHETIC RAW MATERIALS

It is used to make metal zirconium and zirconium compounds, refractory bricks and crucibles, high-frequency ceramics, grinding materials, ceramic pigments and zirconates, etc. It is mainly used in piezoelectric ceramic products, daily ceramics, refractory materials and zirconium bricks, zirconium tubes, crucibles, etc. for precious metal smelting.

REFRACTORY MATERIALS

Zirconium oxide fiber is a polycrystalline refractory fiber material. Due to the high melting point, non-oxidation and other high-temperature excellent properties of ZrO2 itself, ZrO2 fiber has a higher use temperature than other refractory fiber varieties such as alumina fiber, mullite fiber, and aluminum silicate fiber.

GAS TURBINES

The application of plasma sprayed zirconium dioxide thermal barrier coatings in aviation and industrial gas turbines has made great progress and has been used in the turbine part of gas turbines to a certain extent.

CERAMIC MATERIALS

Because zirconium oxide has a large refractive index, high melting point and strong corrosion resistance, it is used as a raw material in the kiln industry. Piezoelectric ceramic products include filters, speakers, ultrasonic and hydroacoustic detectors, etc. There are also daily-use ceramics (industrial ceramic glazes), zirconium bricks and zirconium tubes for precious metal smelting, etc. Nano-scale zirconium oxide can also be used as a polishing agent, abrasives, piezoelectric ceramics, precision ceramics, ceramic glazes and matrix materials for high-temperature pigments.

OTHERS

In addition, zirconium oxide can be used in the manufacture of incandescent gas lampshades, enamels, white glass, refractory crucibles, etc. X-ray photography. Abrasive materials. Used together with yttrium to manufacture light source lamps in infrared spectrometers, thick film circuit capacitor materials, and piezoelectric crystal transducer formulas.
