structure. Phase diagram for the Co-Sb system is well known [ 1 ]. CoSb 3 is the δ phase, which is stable up to 874 °C. Above this temperature it undergoes peritectic decomposition into liquid and CoSb 2 γ phase, stable up to 936 °C. In recent times

Thermal dehydration and decomposition studies of metal salts hydrates have gained significant importance [ 1 , 2 ]. One of the reasons is the ability to receive, in these processes, materials with high
Thermal decomposition of natural pyrite (cubic, FeS2) has been investigated using X-ray diffraction and57Fe Mössbauer spectroscopy. X-ray diffraction analysis of pyrite ore from different sources showed the presence of associated minerals, such as quartz, szomolnokite, stilbite or stellerite, micas and hematite. Hematite, maghemite and pyrrhotite were detected as thermal decomposition products of natural pyrite. The phase composition of the thermal decomposition products depends on the temperature, time of heating and starting size of pyrite crystals. Hematite is the end product of the thermal decomposition of natural pyrite.
Results are presented on the thermal behaviour of two derivatives of malic acid. The decomposition intermediates obtained at about 400‡C were identified as derivatives of malonic acid. For some individual thermal decomposition steps, the values of the non-isothermal kinetic parameters were determined.
