Ginstling-Brounshtein model

Carter further improved the Ginstling-Brounshtein model by... 

The Ginstling-Brounshtein model was used in constructing an Arrhenius plot for the reaction between strontium carbonate and anatase. Arrhenius plots were constructed for the reaction between strontium carbonate and rutile (see Fig. 8) using both the contracting cylinder model and the nucleus growth model with m = Activation energies calculated from the two reac-... 

Isothermal TG studies [33] of the thermal decompositions in Nj of BaOj (763 to 883 K) and SrOj (653 to 803 K) showed overall deceleratory kinetics described by the Ginstling-Brounshtein diffiision model (low a) and the first-order equation at higher nr values, is, values were 185 5 kJ mol for BaOj and 119 2 kJ mol for SrO. Non-isothermal kinetic analyses gave similar is, values for both decompositions (165 5 kJ mol ). It is suggested [33] that the rate of removal of oxygen from the peroxide by diffusion could be drastically altered by the formation of a crystalline layer of oxide on the reactant surface.
