表面活性剂对三水碳酸镁晶须形貌的影响研究

Study on the Effects of Different Surface-active Agent on the Morphology of Nesquehonite Whisker

采用低温液相法制备三水碳酸镁晶须晶体,研究了不同表面活性剂对晶须晶体形貌的影响,研究发现:有机表面活性剂的作用效果没有无机表面活性剂的作用效果好,采用磷酸二氢钾作为表面活性剂时,制备的三水碳酸镁晶须结晶发育完整,晶须长径比大。

The nesquehonite whisker is synthetized by low-temperature aqueous solution polymerization. Effect of different surfactants on crystal whisker morphology have been studied. The study finds that the inorganic surfactant is better than organic, especially when using the potassium dihydrogen phosphate as the surfactant, the whiskers grow more complete and the length-diameter ratio are more larger.
