The influence of KOH mineralizer on the hydrothermal modification of Mg(OH)_2 was investigated. X-ray diffraction, scanning electron microscopy, thermo-gravimetry and specific surface area analyses indicated that KOH played a key role in the recrystallization of Mg(OH)_2. It was found that the morphology and dispersion of Mg(OH)_2 particles ? improved significantly with an increase of KOH concentration from 1 to 4 mol/l. 收起
