Mullite formation kinetic from a porcelain stoneware body for tiles production

The growth of mullite (3Al2O3•2SiO2) in a porcelain stoneware body for tiles production has been investigated using differential thermal analysis (DTA). The activation energy calculated by both isothermal and non-isothermal treatments is 599 and 622 kJ mol-1 respectively. The growth morphology param...
