摘　　要：考察了在硫酸钙晶须制备过程中氯化钠和氯化钙杂质对晶须形貌的影响。对制得的硫酸钙晶须进行了SEM和XRD分析。结果表明,随着氯化钠和氯化钙浓度的增大,晶须的直径增大,长度变短,长径比减小。The influence of impurity on the surface morphology of calcium sulfate whiskers in sodium chloride and calcium chloride solutions were studied by the SEM and XRD.The results show that the concentration of sodium chloride and calcium chloride make the diameter of calcium sulfate whiskers bigger and shorter length.The length/diameter ratio reduced.

关 键 词：氯化钠 氯化钙 硫酸钙晶须
