Thermogravimetric study of precursor complexes for nanoscale films of tin dioxide

The results of thermogravimetric studies of two precursors’ complexes of tin dioxideused for sensitive elements of sensors permitted to establish and to compare the basic thermal decomposition stages. Differences in the decomposition processes of the complexes exist due to the differences of their structure, that is: presence (in the Complex 1) or absence (in the Complex 2) of a coordinated water molecules. At the thermal decomposition of the complex, presence of water helps to loosen the matter of complex and gives tin dioxide films with nanoscale grains.
