Magnesium hydroxide is a colorless hexagonal column crystal or white powder, hardly soluble in water and alcohol, soluble in dilute acid and ammonium salt solution, and the aqueous solution is alkaline. What are the factors that affect the synthesis of magnesium hydroxide by precipitation? Here is a brief introduction for everyone.
1. The amount of ammonia water has an important influence on the morphology and size of the prepared magnesium hydroxide product.
On the one hand, it is related to the crystal structure of magnesium hydroxide itself, and the irregular aggregate structure is loose and does not seem to be fully developed, which provides clues for further growth of the spherical particles.
2. In addition to the amount of ammonia water, the reaction temperature also has an important influence on the morphology and size of the prepared magnesium hydroxide product.
Other conditions were maintained, and magnesium hydroxide of different morphology was obtained by adjusting the reaction temperature. Therefore, the reaction temperature plays an important role in the formation of the spherical magnesium hydroxide.
