The study of their thermal properties (DSC, TG/DTG, FT-IR) showed that they might be used as chemically stable precursors in the preparation of fluoride glasses. Hydrofluoric acid in solution was chosen as a mild fluorinating agent. This newly proposed technique of fluorinating allowed to obtain high quality ZBLALi glass which presents the advantage of higher thermal stability and homogeneity in comparison with the glass obtained using individual commercial fluorides.87-93engfluoride glassesglass precursorsxerogelsArtigo10.1023/B:JTAN.0000017331.26326.54WOS:000189208500009Acesso restrito6475585105456744
