CERATOS/TITANATOS DE SAMARIO PARA GENERACIÓN ALTERNATIVA DE ENERGÍA Y COMO RECUBRIMIENTOS DE ALTA TEMPERATURA
Journal Title: AvaCient - Year 2022, Vol 13, Issue 02
Abstract
This study reports the mechanosynthesis and characterization of materials based on samarium ceratestitanates, for their application as TBC (Thermal Barrier Coatings) and as electrolytes in Solid Oxide Fuel Cells. The samples obtained by mechanical milling in a planetary ball mill were characterized by powder XRD to establish the ideal reaction time (20 hours) and then to evaluate their crystallinity and the stability of the phases obtained after thermal treatments at high temperatures (900 and 1200 °C). The study of thermal stability from room temperature to 1050 °C was carried out by thermal analysis (ATG/ATD). For microstructural analysis (FE-SEM) and thermal and electrical properties (laser flash and impedance spectroscopy, respectively), pellets were fabricated by uniaxial pressing and sintered at 1200 °C. The results prove that it is feasible to obtain these materials by mechanical milling, while their low thermal conductivity and high ionic conductivity corroborate their viability for their application in TBCs and electrolytes in fuel cells.
