Zirconia Pellets (ZrO2 Pellets)

Physical and chemical properties

Zirconia (ZrO₂) The natural zirconia mineral raw materials mainly include baddeleyite and zircon. Zircon is a deep-seated mineral of igneous rock, with pale yellow, brownish yellow, yellow-green color, melting point: 2700°C, specific gravity 4.6-4.7, hardness 7.5, with strong metallic luster, and can be used as a raw material for ceramic glaze. Relative molecular mass: 123.22. CAS accession number: 1314-23-4. Density: 5.89g/cm3 (different content, different density, subject to actual requirements)

Application

1. Zirconia: mainly used for piezoelectric ceramic products, household ceramics, refractory materials and zirconium bricks, zirconium tubes, crucibles, etc. for smelting precious metals. Also used in the production of steel and non-ferrous metals, optical glass and zirconium dioxide fibers. It can be used as an efficient high temperature thermal insulation material.

2. Zirconia fiber: In the fields of aerospace, national defense and military industry, atomic energy, etc., it is used for ultra-high temperature heat insulation protection materials and ceramic matrix composite reinforcement materials.

3. Used as an inert filler and extender for plastics, rubber, latex, etc.

4. For the manufacture of functional ceramics and structural ceramics, or as abrasive materials.

5. Because of its high refractive index, high melting point and strong corrosion resistance, it is used as raw material for kiln industry. Piezoelectric ceramic products include filters, speakers, ultrasonic underwater acoustic detectors, etc. There are also daily-use ceramics (industrial ceramic glaze), refractory materials, zirconium bricks and zirconium tubes for precious metal smelting. It is also used as a pigment in steel, non-ferrous metals, optical glass, zirconium dioxide fibers and cosmetics.
