Abstract
Emanation Thermal Analysis (ETA) was demonstrated as a tool for the characterization of microstructure changes of a sol—gel precursor for silica—titania layers deposited on the glass plate to be used as planar waveguides. Temperature ranges of 280–330 and 380–500°C, respectively, in which the densification of the layers took place, were determined by ETA under in situ conditions of the sample heating. Results of thermogravimetry were compared with the ETA data.
