This project plans to conduct fundamental studies of the sintering behavior of two model two-phase ceramic systems. One system is the alumina containing sub-micron SiC particles. It is used to test the particle pinning theories of grain growth inhibition. Another system is the slumina containing calcium aluminosilicate glass. It is designed to investigate the effect of pore size distribution on the kinetics of densification during liquid phase sintering. %%%%% This proposal uses two model systems of two-phase ceramic materials, and investigate their sintering behaviors. Detailed experimental characterizations of the material system during the sintering are used to be compared with know theories. Through this approach, better understanding of the sintering of two-phase ceramic systems can be achieved.

该项目计划对两种模型两相陶瓷系统的烧结行为进行基础研究。 一种系统是含有亚微米SiC颗粒的氧化铝。 它用于测试抑制晶粒生长的粒子钉扎理论。 另一种系统是含有钙铝硅酸盐玻璃的氧化铝。 它旨在研究孔径分布对液相烧结过程中致密化动力学的影响。 %%%%% 该提案使用两相陶瓷材料的两个模型系统，并研究它们的烧结行为。 烧结过程中材料系统的详细实验表征用于与已知理论进行比较。 通过这种方法，可以更好地理解两相陶瓷系统的烧结。
