Emanation thermal analysis study of synthetic gibbsite - Evaluation of experimental ETA results by mathematical modelling.

Popis výsledku v původním jazyce

Emanation thermal analysis (ETA) was used for thermal characterization of microstructure changes taking place during heating of synthetic gibbsite sample in argon in the range of 25-1200degreesC. Microstructure development and the increase of the surfacearea under in-situ conditions of the sample heating were characterized. The increase of the radon release rate from 130-330degreesC monitored the increase of the surface area due to the dehydration of AI(OH)(3). During heating of the sample in the range450-1080degreesC the ETA results characterized the annealing of surface and near surface structure irregularities of intermediate products of gibbsite heat treatment. The mathematical model for the evaluation of the ETA experimental results was proposed. From the comparison of the experimental ETA results with the model curves it followed that the model is suitable for the quantitative characterization of microstructure changes taking place on heating of gibbsite sample.
