Summary

The mixed oxide route is the most economical and simple way to prepare ceramic PLZT powders. This method was improved, so that it can compete with more sophisticated preparation routes like coprecipitation and the hydrothermal synthesis. The use of titanium and zirconium oxides with particle sizes of 20–40 nm instead of the usual several micrometer sized powders allows the preparation of a homogeneous PLZT powder. Due to the higher reactivity of the nano powders the calcination temperature could be reduced from 900°C to 700°C and the calcination time was reduced to one hour. In the case of microwave calcination the PLZT powder could be calcined at 900°C within 30 minutes. The resulting PLZT particles had diameters of 200–400 nm.
