| Abstract: | Taking basic magnesium sulphate whiskers and sodium hydroxide as raw materials,the proper process parameters are experimentally investigated for magnesium hydroxide whiskers preparation by hydrothermal synthesization.The experimental results show that,satisfactory product of magnesium hydroxide whiskers can be obtained under the condition of 4.0% initial concentration of basic magnesium sulphate whisker,100r/min stirring intensity,180°C reaction temperature, and 4h reaction time.The whisker product of magnesium hydroxide is of less then 0.5μm in diameter and greater than or equal to 15 in slenderness ratio.The whiskers are characterized with smooth surface,straight morphology,small diameter and high purity. |
