使用小角散射，密度测量，X射线衍射，氮吸附，透射和扫描电子显微镜，在纳米结构陶瓷氧化物烧结过程中的微观结构演变进行了研究。具有足够的尺寸和均匀性的样品的可用性允许绝对校准的散射数据，并可能确定的微观结构参数和表面积，是统计学上代表的未受干扰的纳米相形态。一个完全定量的微观结构模型已被开发，并在粉末合成和烧结过程中不同的工艺参数的影响进行了评估。预测可实现的烧结全密度显微结构。
Using small-angle scattering, together with density measurements, X-ray diffraction, nitrogen adsorption, and both transmission and scanning electron microscopy, the microstructural evolution during sintering in nanostructured ceramic oxides has been studied. The availability of samples with sufficient size and uniformity has permitted absolute calibration of the scattering data and made possible determinations of microstructural parameters and surface areas that are statistically representative of the undisturbed nanophase morphologies. A fully quantitative microstructural model has been developed, and the effects of varying processing parameters during powder synthesis and sintering have been assessed. Predictions are made regarding the achievable sintered full-density microstructures.
