Thermal investigation of alumina-based pastes and refractory mixturesd

Ioanna D. Katsavou, Magdalini K. Krokida and Ioannis C. Ziomas


Alumina-based refractories are the most commonly used materials for lining electrical furnaces. Bauxite and aluminate chamotte were selected, bound with aluminate cement, and their thermal stability was studied using differential scanning calorimetry and thermogravimetry. Their loss on ignition, after firing at 1000 °C, was determined. The main changes in mass observed were attributed to the removal of moisture at temperatures up to 140 °C and to the dehydration of calcium aluminate cement at 200–300 °C. Boehmite (500 °C) and bayerite transformations (650–700 °C) were recorded for bauxite samples, while chamotte samples exhibited changes due to goethite conversion to hematite (400 °C) and spinel formation at 900 °C. Water removal was then examined in detail through differential scanning calorimetry tests. Experiments for loss on ignition showed that particle size of refractory bauxite does not affect mass changes during firing, while chamotte samples were found to show greater loss at particle sizes 200–315 μm, due to impurities and low melting point compounds.
