摘要：

Xerogel with cordierite composition Mg2Al3[AlSi5O18] from aluminium and magnesium 2-ethoxyethoxides and tetraethylortosilicate have been prepared, the latter being not previously partially hydrolized. Conditions to obtain not only homogeneous but also sinterable gel have been determined. All the powders derived were characterized by DTA, TG, BET and X-ray diffraction. Bulk alpha-cordierite material of 97% from theoretical density have been obtained by sintering.
