The flame retardant magnesium hydroxide powder was prepared by two-step method using magnesium oxide which was calcined by magnesium chloride as raw material. Two-step method consists of hydrating and hydrothermal reaction process. The effects of hydration time, hydrothermal reaction time and temperature, and the concentration of sodium hydroxide on the morphology and structure of magnesium hydroxide had been studied. Special attention was given to the obtaining of platelet-shaped, high purity and highly-dispersible powders. The characterization of magnesium hydroxide powder was investigated by X-ray diffraction (XRD), scanning electronic microscope (SEM), and nitrogen absorption BET analyzer. It is indicated that magnesium oxide has been completely hydrated after 3h. As the hydrothermal temperature and time increased, crystal size became larger and crystalline dispersion became remarkable. Additionally, increasing the hydrothermal additives concentration of sodium hydroxide can significantly improve the degree of crystallization crystals, reduce the microscopic internal strain of crystal, and enhance powder dispersibility.
