                                     Generally, the weight losses in TG showed correspondence with
                              the endothermal effects in DTA. The weight losses were found to be very
                              useful for quantitative measurements. [18]  A comparison of the DTA and TG
                              curves are illustrated in Fig. 7. The DTA curve shows an exothermic effect
                              at 940°C for crystallization that is absent in TG.
