Abstract

The glasses in the system SnF2-SnCl2-PbO-P2O5 are very interesting because their very low melting and processing temperatures combined, in some cases, with a quite satisfactory chemical stability. Experimenting procedures to avoid the PbO reduction glasses were synthesized and some properties were determined, among them Tg and Td, confirming the possibility to melt and process these glasses at temperatures under 500 oC. In a first attempt to determine the basicity of such glasses, verisimilar values were obtained placing them in the domain of the good glass forming compositions. The peaks in the recorded IR spectra were assigned and seem to confirm the glass forming ability of Sn halogenides, which forms tetrahedrons like P..
