Tin oxide based thick film resistor (TFR) compositions were studied by irnmittance spectroscopy (IS) and electron microscopy techniques. Three groups of TFRs, obtained commercially and prepared in the laboratory, were investigated in which the composition was varied by changing the Sn02 content in the glass matrix. In addition, samples made from 100% glass were also studied. The main attention was focused on the samples manufactured by Lapp Insulator Company, for which the conduction mechanism, microstructure, and annealing characteristics were studied in detail...
