Metallalcoholates as ceramic precursors were infiltrated into porous ceramic matrices and decomposed to sinteractive powders. Fully crystalline powders with cluster-like morphology were obtained by microwave heating 2.45 GHz of the precursor whereas amorphous powders were obtained by conventional heating. After sintering the mechanical properties of the infiltrated ceramic are improved as compared to the matrix material. Microstructure modelling of Al2O3 ceramics towards self strengthened materials by metallorganic infiltration and decomposition and by microwave heating is proposed.
