摘要：
A regularly shaped spherical magnesium hydroxide was synthesized through gas-liquid contact method. The structure, morphology, size distribution, and other characteristics of the spherical magnesium hydroxide were characterized by X-ray diffraction, thermogravimetry-derivative thermogravimetry, scanning electron microscopy, and laser particle analysis. Results reveal that the synthesized spherical magnesium hydroxide has good particle dispersion, a particle diameter of D-50=7.41 mu m and a thermal decomposition temperature above 363.6 degrees C. The formation mechanism of the spherical magnesium hydroxide was discussed according to the principle of gas-liquid contact reaction, and the high volatility and easy absorbability characteristics of ammonia.
