Preparation of Fibrous Basic Magnesium Chloride Single Crystal

Article Preview

Abstract:

The preparation of fibrous basic magnesium chloride single crystal was investigated. And the fibrous basic magnesium chloride single crystal samples were prepared by liquid reaction method at the atmospheric pressure. Based on the test results of SEM, TEM diffraction and XRD, the effects of the mole rate of calcium hydroxide to magnesium chloride, reaction temperature, mixing time and ripening time on the preparation of the fibrous basic magnesium chloride single crystal are discussed. And based on the output and the length of the fibrous, the best technological conditions for preparing the fibrous basic magnesium chloride are as follows: (1) the mole rate of calcium hydroxide to magnesium chloride is between 0.35 and 0.4; (2) the reaction temperature is 45 centigrade temperature degree; (3) the mixing time is between 2 hours and 5 hours; (4) the ripening time is between 24 hours and 36 hours. The fibrous basic magnesium chloride single crystal, whose length is about between 30µm and 100µm and whose diameter is about between 0.2µm and 1µm, is obtained.
