Product Description

Product Description

Yttrium oxide stabilized Zirconia spheres
  Yttria-stabilized zirconia is a ceramic material that changes the phase transformation temperature range of zirconia by adding yttrium oxide, resulting in stable cubic and tetragonal crystals at room temperature.
  At room temperature, it has high strength and toughness, good wear resistance, high temperature and corrosion resistance, high stiffness, non magnetic conductivity, and electrical insulation. At 600 ºC, the strength and hardness of zirconia ceramic balls remain almost unchanged, with a density of 6.00g/cm3 and a thermal expansion rate close to that of metals. They can be used in conjunction with metals. Suitable for bearings, seals, etc.

Applications

1. Ball Bearings: Zirconium oxide balls are used as rolling elements in high-performance ball bearings. Their hardness and low friction properties contribute to improved bearing performance, reduced wear, and increased durability, especially in demanding environments.

2. Valves and Pumps: They are used in valves and pumps, where their wear resistance and chemical inertness are essential for maintaining reliable and leak-free operation.

3. Grinding Media: Zirconium oxide balls are commonly employed as grinding media in ball mills and attritors for fine and ultra-fine grinding of materials. They are preferred for their high hardness, which ensures efficient grinding and minimal contamination of the processed materials.

4. Aerospace and Automotive Applications: Zirconium oxide balls can be found in various aerospace and automotive components, such as fuel injectors, bearings, and flow control devices, where their wear resistance and mechanical properties are highly beneficial.

5. Chemical Processing: Zirconium oxide balls are used in chemical processing applications, such as agitators and reactor vessels, due to their resistance to corrosive chemicals.

6. Food and Pharmaceutical Industry: They are used in the food and pharmaceutical industries, particularly for grinding and mixing applications, because they are non-reactive and can withstand high temperatures and harsh cleaning processes.

7. Precision Instruments: Zirconium oxide balls are used in precision instruments like flow meters and measuring equipment where the accuracy and longevity of components are crucial.

8. Medical Devices: Zirconium oxide balls are used in medical devices and equipment, such as check valves in medical pumps, where biocompatibility and wear resistance are required.
