【Abstract】 A method for the preparation of hexagonal plate aluminum hydroxide is introduced.The factors of effecting on the crystal shape of aluminum hydroxide,such as additives,decomposition temperature,time,and rate of sodium aluminate,and the property of aluminum hydroxide are studied.The results show that hexagonal plate aluminum hydroxide with average sive of about 2 μm,whiteness over 95% and specific area of 6.5～8 m 2/g,which is suitable for the use of painting of paper-making,can be obtained through proper control of decomposition conditions.更多还原
