Zircon powder

ZrO2 powder

In addition to the product ZYP from zircon, we offer a range of powders with different particle sizes.

Melted zirconia

Yellow powder obtained by melting, organic binder-free with good chemical stability. It is produced by fusion.

Applications

  • Ceramic part
  • Pigment
  • Additive in the glass industry
  • Refractory product

Monolithic zirconium dioxide

Non-toxic white powder, stable in alkaline and acid solutions (except for high concentrations of H2SO4, HF and H3PO4). Contains no binder. Unlike melted zirconia powder, zirconium dioxide powder is produced chemically.

Applications

  • Ceramic part
  • Electronic
  • Additive in the glass industry
  • Jewellery
  • Polishing filler
  • Fireproofing product

Pulver aus Zirkonoxidfaser

ZYP powder is an ultra-fine, highly reactive powder composed of zirconia stabilised with yttrium oxide. It is available in two different specific surface sizes: the ZYP-30 has a surface area of 25 to 35 m2/g, while the ZYP-55 has a specific surface area of 50 to 60 m2/g. Sintering of ZYP powder particles starts around 900°C and it is possible to create zirconia ceramic parts approaching theoretical density using ZYP at only 1450˚C.

Properties

  • Extremely high environmental stability
  • Stabilized with 10% yttrium oxide
  • Low sintering temperature
  • Pre-sintered and binder-free

Applications

  • Filtration
  • Manufacture of oxygen sensors
  • Thermal barrier coatings for gas turbines and diesel engines
  • Grain growth inhibitor for non-oxide ceramics
  • Polishing
