The glow curve sensitivity of several alumina grains are defined by (i) a maximum centred at about 165°C that can be deconvoluted into two first order kinetic peaks at 157 and 177°C and (ii) a broad structure over 200-220°C that suggests a continuous trap distribution system. The isolated grains, analysed by means of X-ray diffraction, are composed of 43% of alumina (A12O3), 22% of mullite [72% of A12O3 and 28% of Si02], 12% of leucite (KAISi206) and 23% of sillimanite [Al 203Si02]. The sample characterization has been performed using X-ray fluorescence and scanning electron microscopy.engjournal article0973-7669http://dx.doi.org/10.1007/s12034-008-0142-xopen access661.862Ceramicsaluminium oxideX-ray diffractionscanning electron microscopythermoluminescenceMineralogía (Geología)Física de materiales2506.11 Mineralogía
