Thermal decomposition of Zr/KClO4 priming compositions containing different concentration of additives, such as graphite, Fe2O3 and Al2O3 have been studied by DSC/TG techniques. The firing characteristics of these primer mixtures have also been examined by Bruceton
test and by adiabatic calorimeter. The results of these experiments suggest that strong interaction has been occurred between
KClO4 and Fe2O3 in the solid state.

Vitreous solder glasses, such as Mansol #40 and FEG-2002, are commercialized solder glasses, which are compression sealing
glasses that can be used to solder materials with expansions between 55-68⊙10-7°C-1, such as Al2O3.
In order to understand and tailor the thermal behaviour of solder glasses, cylindrical-like glasses were first carefully ground
with a stainless steel mortar and pestle. Initially, no exothermic or endothermic data were obtained from the DTA/DSC curves
except those relating to melting. However, exothermic peaks appeared after the glass samples were re-melted. In this work,
kinetic parameters such as the activation energy, and the morphology of the devitrification mechanisms for two kinds of solder
glasses were also investigated, using non-isothermal DTA techniques. The activation energies ranged from 220 to 235 kJ mol-1 and the devitrification mechanism parameters were close to 1. This indicates that the devitrification mechanisms of the two
kinds of solder glasses involve surface nuclei.
