【摘要】 本文研究了水合碱式硫酸镁MgSO4·5Mg（OH）2·3H2O（以下称MOS）晶须的水热合成。良好的晶须可通过MgSO4·7H2O和Mg（OH）2间的水热反应生成。文中研究了各种合成条件对合成过程和产物品质的影响。当反应体系在温度为130℃～170℃、压力为304.0～810．4kPa的条件下，合成出的晶须具有很高的纯度，产率达90％以上，纤维长可达200μm，纤维直径为0．8～1．2μm。更多还原

【Abstract】 The hydrothermal synthesis of hydrous magnesium oxysulfate (MOS) whisker has been investigated. The optimum MOS whisker was synthesized via the hydrothermal reaction between MgSO4. 7H2O and Mg(OH)2 at a temperature range of 130-170℃ and at a pressure range of 304. 0-890. 6kPa. The effect of various reaction conditions and factors have been investigated to optimize the quality of the whisker. The synthsized MOS whisker has a high purity and the production yield exceeded 90%. The whisker shows a length of 200μm and a diameter of 0.8- 1. 2μm.更多还原
