Properties of SnO-B₂O₃-SiO₂ Lead-Free Glass Powder

Abstract:

SnO-B₂O₃-SiO₂ glass powders, in which the different contents of SnO and B₂O₃ were 35% ~ 70%wt and 26% ~ 61% wt respectively, were prepared through high-temperature melting, water quenching and Ball milling. XRD showed that the performance of forming glass was very good and the range of extension was very wide. The effect of the contents of SnO and B₂O₃ on Tg, acidoresistant and density of prepared glass was studied. IR showed that it generates the heavy metal oxide generated glass. The density of glass powder decrease with increase of B₂O₃ content, but increase with increasing SnO content. SnO-B₂O₃-SiO₂ glass had excellent chemical stability. Differential thermal analysis (DTA) shown that, with increasing SnO content, glass transition temperature first lower and then decreased.
