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
