Abstract—

We propose a mechanism capable of describing phase transformations during the hydrothermal treatment of micron- and nanometer-sized γ-Al2O3 and Al(OH)3 powders, identify the steps of the process, and demonstrate the role of water with a small heat of vaporization in the hydrothermal treatment process.

Keywords:

mechanism water with a small heat of vaporization phase transformations γ-Al2O3 aluminum hydroxide boehmite
