Which Factors Affect Magnesium Oxide in Precipitation Method?

by Allen Hu magnesium oxide supplier

The dosage of ammonium hydroxide has important impact for the magnesium oxide’s morphology and size. When the dosage of ammonium hydroxide is 10ml, it can gain sheet structure with 1-2μm. It has something to do with crystal structure and properties of magnesium oxide. When the dosage of ammonium hydroxide achieves 7ml, it has sheet aggregation. The structure of this kind of irregular aggregation is loose. What’s more, it looks do not grow to full size, and can provide some cues for the further growth of particle.
Expect for the dosage of ammonium hydroxide, the reaction temperature also has important impact for the magnesium oxide’s morphology and size. Remaining other conditions, it can generate magnesium oxide with different morphology through adjusting reaction temperature. When the reaction temperature is 70℃, it can gain disk type construction with 1 μm radius. When the reaction temperature decreases to 50℃, it produces rosettes structure which is consisted by nanosheet. Therefore, the reaction temperature plays an important role.
