Abstract
The invention relates to a preparation method of a basic magnesium sulfate whisker. The preparation method comprises the following steps of dissolving diethanol amine, ammonium sulfate and magnesium chloride into deionized water; then, placing the mixed liquor into a reaction kettle to react at the temperature of 180-220 DEG C for 4-24h; standing for 1-2 days, and finally, carrying out after-treatment to obtain the basic magnesium sulfate whisker. The preparation method has the beneficial effect that the basic magnesium sulfate whisker with good dispersity can be prepared by using the simple method.
