bound water from the ST 50 and ST 70 samples proceeds at lower temperatures and the inflection point occurs at 110 °C ( Fig. 2 ). The other part of the water desorbs monotonically without visible stages pointing to a quick process. However, in the case

–475 K. The thermal anomaly is caused by the solid–liquid phase transition of DPFEB. In the temperature range of 200–445 K and 480–530 K, the heat capacity of DPFEB increases monotonically in a smooth and continuous manner, indicating that DPFEB is stable

conductivity of the EDS, the higher the value of the “break point” [ 1 ]. Conductometric titrations of the EDS, using NaOH, exhibit a monotonic trend, linear for lower concentrations of the titrant, but with a slope that increases for higher concentrations. The

from Gd(NO 3 ) 3 ·6H 2 O decreases monotonically with increasing temperature up to 1000 °C. Surprisingly, the precursor almost completely evaporates at 1000 °C, which is very difficult to explain. The endothermic behavior on the DSC curve also is

results in monotonic diminution of V Σ to 0.09 cm 3 g −1 . As mentioned above, phase composition of treated oxides does not change during first hour of milling and so, their density remains constant. Consequently, coalescence (consolidation) of
