The structural role of lanthanum oxide in silicate glasses

摘要: Abstract The alleged formation of La-clusters in silicate glasses has received an overall consensus. However, recent and the current experimental results do not support this hypothesis for structural role La2O3 glasses. Therefore, here we propose a new model assignment peaks NMR spectra. All reported could be consistently explained by ascribing to network modifier role. Further, proposed also explain glass compositions literature where it was originally ascribed form La-clusters. mitigated LLPS due increased entropy from increasing number different types Qn units.
