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.

晶粒生长轨迹不同的主烧结曲线：以MgAl ₂ O ₄为例

烧结是高性能陶瓷加工中的关键步骤。密度和晶粒尺寸对陶瓷烧结动力学和最终材料性能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著名工具。然而，传统的MSC理论假定了独特的烧结轨迹，而我们对MgAl ₂ O ₄尖晶石的研究显示出不同的生长响应。已应用Park的MSC理论并将其与常规MSC方法进行比较，以获取具有和不具有不同晶粒生长轨迹的活化能。
