The goal of the investigation in to study the effects of pore size and pore size distribution upon development of microstructure of ceramics processed using solid state sintering techniques. Model final-stage microstructures are tailor made using ultra-high-purity alumina powders containing latex spheres of controlled size, size distribution and amount. These model controlled microstructures include undoped alumina with uniform pore distribution, undoped and nonuniform pore distribution, and sintering models will be tested.

本研究的目的是研究孔径和孔径分布对固体烧结陶瓷微观结构发展的影响。模型最后阶段的微观结构是量身定制的，使用超高纯度的氧化铝粉末，含有控制尺寸，尺寸分布和数量的乳胶球。这些模型控制的微观结构包括均匀孔隙分布的未掺杂氧化铝，不均匀孔隙分布的未掺杂氧化铝，以及烧结模型。
