Zirconium dioxide is a kind of high-grade refractory material, with higher use temperature and better thermal insulation performance than alumina fiber, mullite fiber, aluminum silicate fiber, and high temperature chemical stability, corrosion resistance, oxidation resistance, non-volatile, pollution-free. Zirconia as a refractory material is mainly used in the key parts of large glass tank kilns. Zirconia hollow spheres of different sizes were obtained by melting and blowing zirconia to prepare various high grade heat insulation bricks. The main domestic manufacturers have Luoyang refractory Research Institute.

Application:

1 Used for the production of metal zirconium and zirconium compounds, refractory bricks and crucbles, high-frequency ceramics, grinding materials, ceramic pigments and zirconates.

2 Can be used as an efficient high temperature insulation material.

3 Can be used to manufacture structural ceramics and functional ceramics and artificial gems.

4 Used as a high-purity reagent and infrared spectral band light source, but also used in the preparation of high-purity zirconium salt.

5 Widely used in the manufacture of refractory materials, abrasive materials, ceramic pigments and zirconates.

6 Mainly used in piezoelectric ceramic products, domestic ceramics, refractory materials and precious metal melting zirconium bricks, zirconium tubes, crucible and so on. It is also used in the production of steel and non-ferrous metals, optical glass and zirconia fibers. It is also used in ceramic pigments, electrostatic coatings and baking paints. Used in epoxy resins to increase corrosion of heat-resistant saline.

7 Used in atomic energy industry, national defense industry, electronic components, ceramic color agents, high temperature resistant materials, etc.

8 White heat gas lampshade, enamel, white glass, refractory crucible, etc. X-ray photography. Abrasive material. Together with yttrium, it is used to manufacture light source lamps in infrared spectrometers, thick film circuit capacitive materials, and piezoelectric crystal transducers. Nanoscale zirconia is used as a substrate for polishes, abrasive particles, piezoelectric ceramics, precision ceramics, ceramic glazes and high-temperature pigments. High purity grade 4N is used as an additive for special glass and optical fibers, glass sheets for high refraction electron microscopy and energy saving light sources.
