Vidros condutores à base de boratos, silicatos e sílico-sulfatos de íons de metais alcalinos foram preparados a partir da mistura apropriada de pós de óxidos, carbonatos e sulfatos, Eles foram produzidos a partir da fusão e resfriamento rápido em um forno de carbeto de silício de ate 1400ºC. Estes materiais foram analisados pelas técnicas de condutividade em corrente contínua (CC) e por Espectroscopia de Impedância (EI) nas caracterizações elétricas, por Difração de Raios X (DRX) para análise estrutural, Absorção Ótica (AO) par verificar a transmitância e pelas técnicas de Espectroscopia de Emissão de Chama (EEC) e Retroespalhamento de Rutherford (RBS) para identificar as composições. Os difratogramas de Raios X mostraram que se tratam...
