TSEE is used today in various fields of solid state physics. We applied this technique to gain an understanding of the mechanical and thermal effects affecting inorganic solids during the preparation phase. The work carried out supplements earlier experiments conducted in our laboratory on the detection by thermoluminescence of defects created in solids, and considers the possiblity of applying TSEE to the study of the reactivity of solids. This paper describes the different stages in the preparation of alumina and attempts to correlate their effects on triboemission glow curves and TSEE emitted after irradiation.
