Evaluación de óxidos minerales para pigmentos y recubrimientos vítreos en cerámicas de CERART-UTPL

Abstract

Abstract:The purpose of this research project was to analyze and evaluate mineral oxides and vitreous coatings distributed in certain locations in Ecuador. Some of the pigments were extracted from the Piuntza sector and Camarones beach, while the material analyzed for vitreous coatings was extracted from the smelting processes of the Mineral Beneficiation Laboratory. The materials used were: ochre (M1), limonite (M2), ferrotitaniferous sands (M3), copper wires (M4), and smelting slag (M5). Based on the study and evaluation, both chemical (XRD) and mineralogical (XRF) characterization were performed, as well as particle size analysis of each sample to determine the type of minerals they contain and their mesh size to determine particle distribution. The results obtained from each of the samples were feasible and favorable, resulting in varying shades that were different from the colors the company uses to make its ceramics.
