DESIGN OF EXPERIMENTAL ROUTES AND DATA-PROCESSING FOR THE DETERMINATION OF THE DEPTH-DISTRIBUTION OF ENERGY IN REAL SOLIDS

No adequate thermodynamic definition of non-equilibrated solids is ava ilable at present. In this paper a method is suggested for the energet ic characterization of solids by estimation of the distribution of the differential molar internal energies - as they appear during the brea kdown of sample e.g. by chemical reaction, i.e. the 'depth distributio n of differential energies' (DDE) of samples. Thermodynamic considerat ions are presented for approximating this quantity - and experimental possibilities proposed to attain the needed input information by therm oanalytical methods. Application of the suggested procedure is suppose d to contribute to the better understanding of structure - energy - re activity relations in real solids.
