Zirconium Oxide

Zirconium Oxide granules is a kind of inorganic material with the chemical formula of ZrO₂ and the appearance of white or yellowish granules, which has the physical and chemical properties of high melting point, high hardness, good chemical stability, low thermal conductivity, good biocompatibility, etc. It has important applications in ceramics, electronics, refractories, coatings, biomedicine and other fields.

Characteristics

Chemical Formula: ZrO₂

Molecular weight: 123.22

CAS No.: 1314-23-4

Appearance: Usually white or light yellow granules

High melting point and high hardness: It has a high melting point of about 2700℃, which makes it still maintain good stability under high temperature environment, meanwhile, zirconia particles have high hardness, which makes it have good wear resistance, and can be used to manufacture parts that need high wear resistance materials.

Chemical stability: at room temperature, zirconium oxide has good chemical stability to most acids, alkalis and organic solvents, and is not easily corroded, and this stability enables it to be used in a variety of harsh chemical environments.

Low thermal conductivity: zirconium oxide has a relatively low thermal conductivity, a characteristic that makes it an excellent thermal insulation material, which can be used to manufacture high-temperature thermal insulation parts or thermal insulation coatings to reduce heat transfer.

Good biocompatibility: zirconium oxide has good biocompatibility and has no obvious irritation or toxic reaction to human tissues, so it has a wide range of application prospects in biomedical fields, such as dentistry and orthopedics.

Applications

Ceramic industry: as an important additive or main component of ceramic materials, it can significantly improve the strength, toughness and wear resistance of ceramics, and is widely used in the manufacture of ceramic knives, ceramic bearings, ceramic valves and other high-performance ceramic products.

Electronic materials: Zirconium Oxide can be used in the manufacture of electronic ceramics, capacitors, thermistors and other electronic components, its high dielectric constant and low loss characteristics make it an important application in the field of electronics.

Refractory materials: due to its high melting point and good chemical stability, zirconia particles are often added to refractory materials to improve the refractory material’s high-temperature resistance and resistance to erosion, used in the manufacture of high-temperature furnace linings, refractory bricks and so on.

Coating industry: Zirconium Oxide can be added to coatings to improve the hardness, abrasion resistance and corrosion resistance of the coatings, and also increase the heat insulation properties of the coatings, which can be used to manufacture high-temperature resistant coatings, abrasion-resistant coatings and other special coatings.

Biomedical field: in dentistry, zirconia particles can be used to manufacture all-ceramic crowns, bridges and other restorations, and its good biocompatibility and aesthetics have attracted widespread attention; in orthopedics, it can be used to manufacture artificial joints, bone implants and so on, and it has good biological activity and mechanical properties.
