Revealing the growth mechanism of ruthenium oxide in glass melt: the effects of alkali metals on crystal growth
摘要
Na induces the formation of acicular RuO2 in the glass melt, and the effect of Cs on the precipitation of RuO2 is not clear. In this study, sodium ruthenate (NaRu) and cesium ruthenate (CsRu) were prepared by quenching experiments, and RuO2-containing waste glass was prepared by calcination of glass surfaces. The results showed that both CsRu and NaRu induced the formation of RuO2 in the glass melts, with rod-like and acicular morphology, respectively. It can be inferred that alkali metals play an important role in the formation of RuO2 with different shapes.
