| Abstract: Dispersive flame retardant type Mg(OH)2 were prepared via the addition of mineralizer into the precursor of Mg(OH)2-xClx obtained with solutions of Ca(OH)2 and MgCl2 in rotor-stator reactor (RSR). Mg(OH)2 crystals were characterized by XRD, SEM, TG. The results show that different mineralizers have different levels of effects on the hydrothermal growth of Mg(OH)2 crystals. Comparing with others, when KOH is used as mineralizer, it is prone to strengthen the growth direction of Mg(OH)2 crystal face. When the concentration of KOH are increased, the micro-strain could be decreased, the crystal structure becomes more stable, plate thickness of Mg(OH)2 crystals is increased, and highly dispersed flame retardant type Mg(OH)2 could be prepared accordingly. |
