In filling plants for cosmetics, special requirements must be met to maintain hygienic conditions as during the filling process no foreign substances may be allowed to get into the cosmetics that could cause any health impairment when the cosmetics are used. Plant parts in contact with the product are therefore equipped with components made of high-performance ceramics on oxide or non-oxide ceramic basis such as Al2O3, doped ZrO2, Al2O3-ZrO2 mixed ceramics and Si3N4 at least in positions exposed to high mechanical, thermal or chemical stresses.

In the following is a general overview of selected material properties relevant to such applications:

  • Purity: ≥99,5 %
  • Density: >98 % of theoretical value
  • Mean bending strength: 350 – 1100 MPa
  • Mean compressive strength: 2000 – 3500 GPa
  • High wear resistance
  • Durable edge sharpness
  • High edge stability
  • High geometric precision to the tolerance range of 0.001 mm
  • Surface roughness: Ra value ≤0,01 µm
  • Piston-cylinder pairs for seal-less operation
  • Resistance to high temperatures to the cryogenic range
  • High thermal shock resistance
  • Material-dependent high or low thermal conductivity
  • Pronounced shape stability
  • Resistance to chemical corrosion
  • Regulatory approval
  • Ability to form force, form-fit, and substance-to-substance bonds with materials of the same type, plastics and with metals
