摘要
采用硝酸法制备了拟薄水铝石 ,讨论了成胶温度和老化温度对拟薄水铝石结晶度和孔径分布的影响。实验结果表明 ,在实验温度 (4 0～ 90℃ )范围内 ,较高的成胶温度和老化温度下制备的拟薄水铝石结晶度较高 ;较高的成胶温度制备的拟薄水铝石孔径较大 ,孔径分布也较集中。
Pseudo-boehmite was prepared by nitric acid process. The effects of gel- formation and aging temperature on crystallinity and pore size distribution of product were discussed. The experimental results showed that in the range of 40～90 ℃, the pseudo-boehmite had higher crystallinity while gel- formation and aging temperature were higher,and the pore size of pseudo-boehmite was larger and pore size distribution was more collective while gel-formation temperature was higher.
