Ceramic beads

High temperature ceramic beads

Overview: Ceramic Beads

Final Advanced Materials supplies three varieties of ceramic beads. 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.

Applications of Ceramic 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 Ceramic Beads

  • Exceptional hardness
  • Strong resistance to friction and wear
  • High elastic modulus
  • High chemical, thermal and mechanical resistance
  • Strong electrical insulating properties
  • Low porosity

Our range of Ceramic Beads

99.7 % Alumina Oxide

The 99.7 % alumina oxide beads are very resistant to wear, heat and corrosive environments. They retain good dimensional stability up to 1,000 °C. Alumina resists oxidation and is tolerant to water, salt solutions and many chemicals and acids.

92 % Alumina Oxide

The composition of these spheres differs slightly from that of previous spheres of pure alumina, with a reduced alumina content of 92 %. As a result, these spheres are more cost-effective. This product is also distinguished by increased abrasiveness and reduced thermal output.

Zirconium oxide stabilized with cerium

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.
