The sol gel route allows powder-less processing of glasses and ceramics. Sol gel chemistry provides mild conditions so that organic species can be mixed with the inorganic precursors, leading to the formation of hybrid organic-inorganic systems. In the present work silica glasses were prepared by sol gel technique. The structural properties of silica glasses has been investigated with Fourier Transform Infrared Spectroscopy (FTIR), since Infrared spectroscopy may probe the nature of the bond between the metal cation and its surrounding oxygens and can distinguish the bonding between metal cations with oxygen.
Infrared spectra were measured for the structural study of the Sodium-lead-bariumaluminum phosphate glass since infrared spectroscopy may probe the nature of the bond between the metal cation and its surrounding oxygens, and can distinguish those metal cations which exhibit a predominantly covalent interaction with oxygen from those metal cation which exhibit mainly ionic interactions with the polyphosphate anionic chains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
