氧化铝绿色样品的强度，通过单轴向压制粉末喷雾干燥与两种粘合剂，如聚（乙二醇）或聚（乙烯醇）进行了讨论（i）的喷雾干燥颗粒的聚合物丰富的外层的粘合性能和（ii）该层的机械性能。当粘结剂的玻璃化转变温度增加时，观察到从晶内到晶间断裂的转变。采用经典的威布尔统计方法研究了粘结剂对绿色制品中缺陷尺寸分布的影响。
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 properties 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 temperature of the binder increases. The influence of the binder on the defect size distribution in the green products is investigated using the classical Weibull statistics.
