Zirconium Beads
Final Advanced Materials supplies three varieties of ceramic beads: two in alumina and one in zircon oxid. These beads are distinguished by their high degree of adaptability to challenging environments and their exceptional strength characteristics. These beads are highly rated in the watchmaking, medical and automobile sectors.
Manufacturing
Ceramic is produced from a chemical composition based upon several oxidized raw materials. The resulting powder is compacted, then moulded by dry pressing. The moulding is then sintered at high temperature to develop its polycrystalline ceramic structure.
Zirconium Oxide Beads
Zirconium oxide beads can be used 2 to 3 times longer than metal or carbide beads in highly abrasive and corrosive environment. They are also much heavier than alumina oxide beads.
Applications of Zirconium Beads
- High-precision and high-speed ball bearings
- Hip replacements
- Valves or relief valves
- Measuring devices
- Reference spheres for three-dimensional measuring machines
- Probes for three-dimensional measuring machines
Benefits of Zirconium Beads
- Exceptional hardness
- Strong resistance to friction and wear
- High elastic modulus
- High chemical, thermal and mechanical resistance
- Strong electrical insulating properties
- Low porosity
