Zirconium dioxide (ZrO2)
SUOYI factory developed and manufactured Zirconium dioxide powder(ZrO2) ,is a high-performance ceramic material. Its excellent physical and chemical stability is widely used in many industrial fields.
Zirconium dioxide is usually white, odorless and tasteless crystals. It is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. It is chemically inactive and has high melting point, high hardness (Mohs hardness 8.5), high strength, good wear resistance, high resistivity, high refractive index and low thermal expansion coefficient. It becomes an important high temperature resistant material, ceramic insulation material and ceramic sunscreen, and is also the main raw material for artificial drills.
Physical properties:
Melting point: 2700℃
Boiling point: 4300℃
Flash point: 5000℃
Density: 5.85g/cm3
Appearance: white, odorless and tasteless crystals
Zirconium dioxide has three crystal forms: monoclinic, tetragonal and cubic.
Monoclinic: room temperature ~1170°C, high stability but easy to crack.
Tetragonal phase: 1170~2370°C, high strength, can be stabilized to room temperature by doping.
Cubic phase: >2370°C, used for fuel cell electrolytes.
Pure zirconium dioxide powder: high purity (above 99.9%), used for precision ceramics.
YSZ (yttrium stabilized zirconia): doped with 3-8% Y₂O₃, used for oxygen sensors and thermal barrier coatings.
CSZ calcium stabilized zirconia
Nano zirconium dioxide: particle size <100 nm, used in catalysis, biomedicine and other fields.
