Nessa tese de doutorado apresentam-se resultados de caracterização química, térmica, estrutural, microestrutural e elétrica de vidros e vitrocerâmicas de composição Li1,3Al0,3Ti1,7(PO4)3 (LATP), Li1,5Al0,5Ge1,5(PO4)3 (LAGP) e (LixNa1-x)1,5Al0,5Ge1,5(PO4)3 (LNAGP). Mostrou-se que as composições apresentam nucleação homogênea (Tgr ≤ 0,6), característica que torna possível o controle da microestrutura através de tratamentos térmicos, que no caso foram simples (TTS) e duplos (TTD). Foi obtida em todas as composições estudadas a fase altamente condutora com estrutura tipo NASICON. Fases secundárias também foram observadas, porém sem efeito deletério na condutividade elétrica total. A caracterização elétrica por espectroscopia de impedância...
