论文修改，需要论色摘要，谢谢啊 In order to find a new approach to prepare magnesium hydroxide chloride hydrate (MHCH) and extend the applications of carbonate minerals, one-dimensional (1D) MHCH was controlled prepared in CaO-MgCl2-H2O system via a hydrothermal method. The effects of MgCl2 concentration, molar ratio of CaO to MgCl2 (R), and hydrothermal conditions on the structure and morphology of MHCH were investigated. It is found that MHCH can only be synthesized when the MgCl2 concentration was greater than 3 mol•L-1 and R was less than 0.5. The diameter and radius-length ratio of MHCH increase with the MgCl2 concentration and R, and the optimum conditions to prepare MHCH are [MgCl2]=4 mol•L-1 and R=0.05. The reaction temperature determines the phases of MHCH, where phase 3 (Mg2(OH)3Cl•4H2O) is stable at below 150 oC and phase 9 (Mg10(OH)18Cl2•5H2O) is obtained at above 150 oC. In this reaction system at room temperature, Mg3(OH)5Cl•3H2O and phase 5 (Mg3(OH)5Cl•4H2O) occurred firstly; both of them were converted to phase 3 after aged for 1 d. Phase 3 was further converted to phase 9 during the hydrothermal treatment at 160 oC. |

In this reaction system at room temperature, Mg3(OH)5Cl•3H2O and phase 5 (Mg3(OH)5Cl•4H2O) reacted firstly. Then, both of them were converted to phase 3 1d later. At last, phase 3 was further converted to phase 9 during the hydrothermal treatment at 160 ℃. |
