| 英文摘要 | The supersaturated solution of MgO . 3B(2)O(3)-18% MgSO4-H2O was prepared and kept in a thermostat of (20 +/- 0.1) degreesC. The crystallization processes of Mg-borates from the solution have been studied by the kinetic method. With the aid of simplex optinum method and digital integration as well as runge-kutta digital solution of differential equation system, the experimental data have been fitted and the kinetic parameters have been evaluated by computer. The crystallization kinetic equation has been given. There are two solid phases, Macallisterite (MgO . 3B(2)O(3) . 7.5H(2)O) was firstly crystallized out from the solution and then hungchaoite (MgO . 2B(2)O(3) . 9H(2)O). The solid phases were identified by IR-spectra, X-ray powder diffraction and TG-DSC thermal analysis. |
