论文摘要

烧结是处理高性能陶瓷的关键步骤。密度和晶粒尺寸在陶瓷烧结动力学和最终材料特性上都起着至关重要的作用。主烧结曲线(MSC)是探索烧结模型动力学的知名工具。然而,常规的MSC理论假定了独特的烧结轨迹,而我们对MGAL2O4尖晶石的研究显示出不同的生长反应。 PARK的MSC理论已被应用,并将其与传统的MSC方法进行了比较,该方法在具有和没有不同谷物生长轨迹的情况下获得了激活能。

Sintering is a key step in the processing of high performance ceramics. Both the density and the grain size play a crucial role on the ceramic sintering kinetics and the final material properties. The master sintering curve (MSC) is a well-known tool for exploring sintering models kinetics. However, the conventional MSC theory assumes a unique sintering trajectory, while our study on MgAl2O4 spinel shows dissimilar growth response. Park's MSC theory has been applied and compared with the conventional MSC approach for obtaining the activation energy with and without dissimilar grain growth trajectories.
