Description

Kaolinitic clays are vastly used in ceramic industry. Light coloration burned clays are very useful in the coatings production because of their aesthetic. In this work clay material from Vitoria da Conquista (south-west Bahia, Brazil) was characterized by various techniques. Differential Scanning Calorimetry (DSC) shows a kaolinite characteristic curve with an endothermic peak at 492 deg C, which corresponds to the kaolinite - metakaolinite transformation. Transformation alpha to beta quartz is characterized by a 573 deg C peak. The samples were also characterized by water absorption and x rays powder diffraction. The 1100 deg C burned samples were tested by rupture tension with acceptable results. (author)
