Engineering Physics Annotation << Back Temperature Analysis of Thermogramsof Graphite-Carbonate and Oxide Mixtures.Part 3. Determination of Copper Function Doroshko G.P., Barbin N.M. A variant of modeling the processes of graphite processing by heating with the participation of an element |Cu| on the surface of graphite in the redox process of carbon functionality. Copper activity is estimated as a special appendix (TTA) of the theory of temperature analysis of EDS TA states on the example of studying the increments of ΔTEDS of molecular carbon and CuO in a mixture of carbonates Na2 CO3 , K2 CO3 , Li2 CO3 transition to molecular, until the thermocouple registers the heating of the entire mass. The counting of the temperatures of local shifts of the thermocouple readings recorded by the EDS is carried out relative to the grid of states of temperature periodicity and by the time of development of the technological activation process, from local discrete atomic states by continuous transition to molecular ones, to the moment of thermocouple registration of heating of the entire mass. Keywords: deactivation, initiation, copper, oxidation, heating, temperature analysis, stationarity, periodicity, bridges. DOI: 10.25791/infizik.4.2025.1471 Pp. 29-40.
