| Abstract |
| In the present investigation the synthesis and densification
behaviour of Zr02-9.0 mol% Y 20 3 ceramics lias been
described. Powder preparation was based on the co-precipitation
method. It was found that variation in the precipitation
conditions and washing steps of the precipitated gels
resulted in powder of different agglomerate sizes. The effect
of different precipitations and washing conditions on the
crystallite size of the 600°C calcined powders were examined
by X-ray diffraction. The powders produced were essentially
of the cubic fluorite phase. The ball-milled powders were
analyzed for particle size distribution. Densification behaviour
of the bodies made by slip casting has also been studied. |
