摘　　要：锌系硅酸盐熔体分相的分形学表征孙洪巍，高力明，陈显求，黄瑞福（西北轻工业学院材料工程系７１２０８１）（中国科学院上海硅酸盐研究所２０００５０）ＦｒａｃｔａｌＩｎｔｅｒｐｒｅｔａｔｉｏｎｏｆＰｈａｓｅ一ＳｅｐａｒａｔｉｏｎｏｆＺｉｎｃＳｉｌｉｃａｔｅＭ...A broad phase separation region was revealed by the fundamental investigation on large scale recipes of K_2O (Na_2O)-CaO-ZnO-Al_2O_3-SiO_2 systems.A red bayberry like diserete droplets were found in some high SiO_2 sam ples on given heat treatment conditions,Further studied results shown that this structure appeared to be a fraotal feature with the fractul dimension of D=2.127 computated according to an ideal model designed by ourselve. It has been found that the D changes linearly with the diameter d of micro-grains which clusterred together to form a red bayberry droplet. Computated results shown that D unchanges during growing of red bayberry droplet if d were constant,when d deoreaseg to a given value,D trend to 2,that’s to say,the droplets would get atwo dimension spherical surface when d approaches to a critical value, which characterized the relations between the phase separation red bayberry struoture or temperature and temperature gradient quantitatively.
