Abstract

To process mullite ceramics, diphasic aluminosilicate gel was synthesized from inorganic salts by employing the sol-gel route. The process of mullitization was studied by FTIR, DTA and SEM analysis. The particle size of the mullite ceramics was found to be in the nanometer range. The gel was calcined at 800°C. To the calcined gel, oxides of titanium and vanadium were mixed separately. The powder masses were compacted at 100 MPa pressure and then sintered at different elevated temperatures. The mechanical and microstructural properties of the doped samples were studied, and it was found that both the oxides influenced the process of mullitization positively.
