Abstract：After the brucite,raw material,was calcinated at 340 ℃ in Muffle furnace,the magnesium hydroxide was obtained by hydrothermal reaction,sodium p-toluene sulfonate as inducer.The effect of sodium p-toluene sulfonate on the morphology of Mg (OH)2,and the cyclic performance of the inducer through the hydrothermal solution containing inducer recycle were studied.The results show that sodium p-toluene sulfonate play a similar crystal orientation agent role on the morphology of Mg (OH)2.Sodium p-toluene sulfonate has good performance of usage repeatedly.By changing the hydrothermal solution of 5 mol/L sodium hydroxide solution,the surface polarity and the purity of magnesium hydroxide is improved.
