The invention discloses easily soluble aluminum hydroxide crystal seeds and a preparation method thereof, easily soluble aluminum hydroxide and a preparation method thereof. The method comprises: mixing alumina hydrate and a solvent, and beating to obtain a mixture; The solid content is 100-300 g/L; the pH value of the mixture is adjusted to 7.5-13, and the mixture is stirred and dispersed to obtain seed crystals. Using the crystal seed to prepare easily soluble aluminum hydroxide, the acid solubility is not less than 96.3%, the purity is as high as 99.3%, the impurities are few, and the industrial production is easy. |
