Zircon powder
Zirconia Fibre Powder
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
