Zirconium dioxide (Zirconium Dioxide, referred to as ZrO2) is an important inorganic non-metallic material, which has a wide range of applications in the field of chemical production raw materials. This article will detail the properties and uses of zirconium dioxide.

1. the properties of zirconium dioxide

1. physical properties

zirconium dioxide is white solid powder, with high melting point (2700 ℃), high boiling point (4300 ℃), high hardness (Mohs hardness is 8-8.5) and good thermal stability and other characteristics. In addition, zirconium dioxide has excellent optical properties, such as a high refractive index and a high light transmission.

2. Chemical properties

zirconium dioxide is stable at room temperature and insoluble in water, acids and alkalis, but it can react with many metal oxides, non-metal oxides and acids at high temperatures. In addition, zirconium dioxide also has redox properties and can undergo redox reactions under certain conditions.

2. zirconium dioxide use

1 catalyst carrier

zirconium dioxide has excellent thermal stability and chemical stability, can be used as a catalyst carrier is widely used in petrochemical, environmental protection, new energy and other fields. For example, zirconium dioxide supported noble metal catalysts can be used for automobile exhaust purification to reduce harmful gas emissions.

2. ceramic material

zirconium dioxide has high melting point, high hardness and good thermal stability, can be used as a ceramic material widely used in aerospace, nuclear industry, biomedical and other fields. For example, zirconia ceramics can be used in the manufacture of artificial joints, teeth and other biomedical materials.

3. Refractory

Zirconium dioxide has excellent high temperature stability and corrosion resistance, and can be used as refractory materials in iron and steel, non-ferrous metal smelting and other fields. For example, zirconium dioxide refractory materials can be used to make blast furnace linings to increase the service life of the blast furnace.

4. Photoelectric materials

Zirconia has excellent optical properties and can be used as photoelectric materials in solar cells, photocatalysis and other fields. For example, the zirconium dioxide thin film can be used as a photoelectric conversion layer of a solar cell to improve the photoelectric conversion efficiency of the solar cell.

In short, as an important inorganic non-metallic material, zirconium dioxide has a wide range of applications in the field of chemical production raw materials. With the continuous development of science and technology, the application field of zirconium dioxide will be further expanded.
