摘要

Mullite powders were obtained by calcination of the products hydrothermally treated from mixed alkoxide or mixed sol, containing Al//2O//3:SiO//2 equals 3:2 (molar ratio). Pseudoboehmite-like phase, which contained both Al and Si components, was obtained by the hydrothermal treatment of mixed alkoxide or mixed sol, under 50 MPa at 300-400 degree C for 2 h. The pseudoboehmite-like phase particles from alkoxide were finer and more homogeneous than those from sol. The reaction among Al//2O//3, SiO//2 and H//2O was promoted to form aluminosilicates by the hydrothermal treatment under 50 MPa at 500-600 degree C for 2 h, using sol as a starting material.
