| Abstract: | With bischofite as raw materials and sodium hydroxide as precipitant,magnesium hydroxide was prepared under the normal pressure.We Mainly studied the influence of the hydrothermal reaction time and temperature on the magnesium hydroxide under the conditions of no modifier by taking hydro-thermal treatment of the slurry and using scanning electron microscope,X-ray diffractometer,laser particle analyzer to characteristic the products from morphology,structure and size distribution.The results showed that the ... |
