The effect of titanium dioxide and vanadium pentaoxide additive on the formation and mechanical properties of chemical mullite from aluminosilicate diphasic gel was compared. The diphasic gel precursor was synthesized by sol-gel route using inorganic salts. The microstructure and phase analysis of the sintered masses from the gel precursors were carried out by means of SEM and XRD studies. It has been observed that both the additives improved the mechanical properties of the mullite ceramics.
