Crystallization kinetics of amorphous alumina zirconia silica ceramics

Original language description

Crystallization of amorphous alumina?zirconia?silica ceramics was studied for seven different amorphous materials produced by plasma spraying. The activation energies calculated from DSC traces decrease with increasing SiO2 concentration from 1500 to 900kJ/mol. Values of the Avrami coefficients together with results of the microstructural observations indicate that tetragonal zirconia crystallization from materials containing more than 10 wt.% SiO2 proceeds by a diffusion-controlled mechanism with nucleation occurring predominantly at the beginning of the process. Material with almost no SiO2 exhibited a value of the Avrami exponent consistent with the crystal growth governed by processes at the phase boundary.
