Abstract
The strength of alumina green samples prepared by uniaxial pressing of powders spray-dried with two binders such as poly(ethylene glycol) or poly(vinyl alcohol) is discussed in terms of (i) the adhesive propert ies of the polymer-rich external layer of spray-dried granules and (ii ) the mechanical properties of this layer. A transition from intra- to intergranular fracture is observed when the glass transition temperat ure of the binder increases. The influence of the binder on the defect size distribution in the green products is investigated using the cla ssical Weibull statistics.
