What is the reason for the difference in the solubility index of pseudo boehmite?

We see when we prepare pseudo boehmite,  though using the same raw materials,  different processes produce the pseudo boehmite which has largely different solubility index or peptizing index. Why is this? What is the reason for the difference in the solubility index of pseudo boehmite? Today we will explain why the same raw materials  with different methods of preparation of pseudo boehmite brings different solubility.
1, In the preparation of pseudo boehmite, it will be easy to form the crystal. Because there are many crystal structures in aluminum hydroxide, the different crystal structure of aluminum hydroxide leads to the difference of the peptizing index.
2, Different preparation methods get the different pseudo-boehmite microstructure. Using different preparation methods will be obtained from the corrugated flaky, needle, boat, cubic, diamond-like microstructure of the pseudo-boehmite. The different microstructure result different solubility.
3. In addition, the grain size of the pseudo-boehmite produced by different preparation methods is different, and the gelation performance is also different. The reaction pH, reaction temperature, aging temperature, aging pH value and raw material concentration in the preparation of pseudo-boehmite will affect the growth of the pseudo-boehmite grains.
