AB A Spanish hazardous waste from tertiary aluminiumindustry was used as a raw material for the synthesisof calcium aluminate. An amorphous precursor wasobtained by a hydrothermal method at different values ofpH. The transformation of the precursor in a crystallinealuminate was followed by TG/DTA up to 1300 ºC. Attemperatures between 719 and 744 ºC, the precursorsevolve towards the formation of C12A7 which becomes CAat circa 1016 ºC. Mass spectrometry coupled to thermalanalyser allowed the identification of the decompositionproducts.
