Abstract

The basic magnesium chloride whiskers including type3-1-8, 3-1-6, 9-1-5 and 5-1-3 were synthesized simultaneously in the MgO-MgCl-H2O solution system. The results agree well with the formation mechanism of that the unit of the crystal growth, anion or hydroxyl [Mg–(OH)y]2–y (1 £ y £ 6) and x[Mg–(OH)2] (1 £ x £ 9) were the basic construction of basic magnesium chloride and the reaction temperature and molar ratio of MgCl2/MgO were the important effect factors. The standard molar enthalpies of basic magnesium chloride whisker (type 3-1-8) were obtained from a combination of the results with measured enthalpies of basic magnesium chloride whisker (type 3-1-8) in HCl(aq.) and together with the standard molar enthalpies of formation of MgO(s), MgCl2·6H2O and H2O(l) through the design of thermochemical cycle of basic magnesium chloride.
