The present research compares properties and behaviour of co-precipitated 3Y-PSZ
powders submitted, after co-precipitation, to different milling treatments. The characteristics of the
different products were evaluated by measurement of particle size distribution, thermogravimetric
analysis, X-ray diffraction, specific surface area and scanning electron microscopy analysis. It has
been demonstrated that 1h of attrition milling enables the production of powders with micrometric
particles: the dispersing liquid used on milling has little influence. Crystallization of the amorphous
powder is achieved after 1h of high energetic milling, without any thermal treatment.
