Sol Size Changes During Pseudo-Boehmite Peptization Reactivity

The change rule of sol size during the pseudo-boehmite peptization were explored by using experimental apparatus such as Zetasizer Nano ZS 90,TURBISCAN Lab infrared dispersion steady indicator and TEM.The results show that the optimal range of / molar ratio is 0.15 to 0.30,the sol size is about 77 nm.In the three kinds of pseudo-boehmite sol size measurement method,the smallest sol size measured by TEM,followed by the two others.Increase the / molar ratio and peptization temperature are both in favor of peptization reactivity.
