The surface energy of mineral nanoparticles is a significant factor that affects the thermodynamic and kinetic parameters of their chemical reactions. It plays a particularly important role in lowtemperature and lowbaric processes in retrograde diage

The thermal decompositions of dicitratoborates M1[B(C6H6O7)2]·nH2O (n=0–2, M1=Rb, K, Li, NH4) and M11[B(C6H6O7)2]2·8H2O (M11=Co, Ni, Mn, Cu, Zn, Cd) were investigated by means of TG, DTA and DTG methods. It was found that these thermal decomposit

Perlites from large-scale deposits in the USSR were investigated by a modified DTG method. The technique permits an essentially higher DTG curve resolution in comparison with that of conventional DTG curves obtained with a derivatograph. The investig

A NUMBER of articles have been published dealing with the differential thermal analysis (DTA) of chemical reaction kinetics1–5. Only one of these, however, gives a direct method for determining the activation energy (E) of the chemical reaction4. I
