Abstract: SnO2-based materials are used as sensors, catalysts and in electro–optical devices. This work aims to synthesize and characterize the SnO2/Sb2O3-based inorganic pigments, obtained by the polymeric precursor method, also known as Pechini method (based on the metallic citrate polymerization by means of ethylene glycol). The precursors were characterized by thermogravimetry (TG) and differential thermal analysis (DTA). After characterization, the precursors were heat-treated at different temperatures and characterized by X-ray diffraction. According to the TG/DTA curves basically two-step mass loss process was observed: the first one is related to the dehydration of the system; and the second one is representative to the combustion of the organic matter. Increase of the heat treatment temperature from 500 to 600°C and 700°C resulted higher crystallinity of the formed product.

The Electrical Properties of Semi-Conducting Ceramic Glazes
TL;DR: In this article, the contact resistance between an electrode and the semi-conducting glaze is investigated, and it is shown that this resistance decreases as the applied voltage increases. But even with small currents, disintegration of the glaze often occurs in time, especially in the vicinity of the electrodes, due to local heating effects resulting from contact resistance and non-uniformities in the structure of glaze.
