This proposal has two stated objectives. One was to examine the microstructural development during solidification of a ceramic material in which more than one phase adopts a faceted morphology. A four component silicate system of silica-magnesia-alumina-calcia (SMAC) was selected for this study. The second objective was to gain a better understanding of the visual representation of multicomponent system with a previously developed computer aided design (CAD) program. %%%% This proposal studies the microstructural development during directional solidification. The floating zone technique will be employed. A previously developed computer aided design (CAD) program will be modified to handle systems with components greater than 4. This study will bring better understandings of phase equlibria and the morphological development during the solidification.

这项建议有两个明确的目标。 一个是检查 陶瓷凝固过程中的显微结构发展 一种以上的相采用小平面形态的材料。 硅镁铝钙四元硅酸盐体系 （SMAC）被选入本研究。 第二个目标是 更好地理解 多组分系统与以前开发的计算机辅助 设计（CAD）程序。 %%%% 该建议研究了 定向凝固 浮动区技术将是 就业。 以前开发的计算机辅助设计（CAD） 程序将被修改，以处理组件更大的系统 比4。 这一研究将有助于更好地理解相位 平衡和形态发育过程中， 固化
