| Abstract: | In this paper,commercial purity aluminum chloride and sodium hydroxide were used as raw materials to prepare aluminum hydroxide gel by direct precipitation method.The water-solubility ion in the colloid were wiped off by the aluminum-type mixed resins in the dispersed system and high purity and ultra-fine aluminum hydroxide with good dispersing was obtained.The products were characterized and analyzed through SEM,EDX and DTA-TG. |
