英文摘要: The MgO . nB(2)O(3) (n = 1, 1. 5, 2 and 3)-18%MgCl2-H2O supersaturated solution system were prepared and kept at 20 degreesC. The crystallization processes of different hydrated Mg-borates from MgO . nB(2)O(3)-18%MgCl2-H2O supersaturated solution have been studied by kinetic method and the crystallization kinetic equations were, fitted with the, experimental data,by computer. There were five solid phases, 2MgO . 2B(2)O(3) . MgCl2 . 14H(2)O, 2MgO . 3B(2)O(3) . 15H(2)O, MgO . 2B(2)O(3) . 9H(2)O, MgO . 3B(2)O(3) . 7. 5H(2)O and MgO . 3B(2)O(3) . 7H(2)O in the title-system. All the solid phases were identified by IR-spectra, X-ray powder diffraction and TG-DTG-DSC thermal analysis.
