NANOCOMPOSITES BASED ON LEAD-BORATE GEL GLASSES

摘要

The aim of the study to make comparison between nanocomposites based on PbMoO_4 crystalline phase and lead-borate glassy matrix synthesized by conventional melting and by sol-gel method. Nanoparticles are incorporated in the composites by mixing and sintering of the previously synthesized powdered melt glass and the active components or by introducing during the process of gelling. TEM observations show that when lead-borate gel glass was used as a matrix and batch melting is applied the content of cr-PbMoO_4 phase influences the structural evolution. At gel glass matrix and sintering procedure for 5 wt.% PbMoO_4 the formation of plate well developed microcrystals PbMoO_4 are formed.
