不同条件下硅酸锌结晶形貌的分形维数

MORPHOLOGY OF FRACTAL DIMENSION UNDER THE CONDITIONS OF DIFFERENT ZINC SILICATE CRYSTALLIZATION

对硅酸锌结晶过程中的晶花生长进行了研究,分析析晶温度、析晶点的保温时间、釉层厚度等实验条件对硅酸锌结晶形貌及其分形维数的影响。结果表明,随着析晶温度的增加,结晶形貌的变化趋势由针状或棒状转化为叶片状或圆盘状,分形维数相应发生变化;随着析晶保温时间的增加,结晶产物形貌由针微晶逐渐转化成放射状晶体,尺寸也有明显增大的趋势,分形维数发生相应的变化;随着釉层厚度的增加,结晶产物呈均匀化,致密化,沉积产物的维数有明显减小的趋势。

The growth of the crystalin process of zinc silicate crystallize was studied in this experiment, the influence of crystallization temperature, the hold time of the crystallization temperature, glaze layer thickness on the appearance of crystal and the fractal dimension was investigated. The result showed that, with the increase of crystallization temperature, crystal appearance changes from acicular into a disc--shanped or leaf--shaped, the fractal dimension of the corresponding changes. As the holding time of crystallization temperature increased, the crystal appearance from needly microcrystal gradually transformed into the radial with the change of the fractal dimension. When the glaze layer thickness increased, the crystal become homogenization and relatively compact and the fractal dimension increased gradually.
