Description

The topography of as-quenched and heat treated 58(2Bi2O3-V2O5)-42SrB4O7 glasses measured with confocal microscope.

Samples of compositions: 58(2Bi2O3-V2O5)-42SrB4O7 were prepared from appropriate amounts of Bi2O3, V2O5 and preprepared polycrystalline strontium–borate. SrB4O7 was synthesized via a solid state reaction route that involved heating stoichiometric mixtures of analytical grade SrCO3 and H3BO3 at 1073 K for 12 hours. Samples of glass were prepared by the conventional melt quenching technique. The melting was conducted in alumina crucibles at 1373 K for 2 hours. The melt was poured onto a preheated (573 K) brass plate and pressed by another plate to obtain flat circular disks of 1–2 mm thickness and 20–30 mm in diameter.

Two types of samples were studied: as-quenched and heat-treated. Sample prepared was partially crystallized by heat treating in air at a temperature of 693 K for 3 and 10 hours and then kept the samples in the furnace to cool to room temperature.

The microstructure of all samples was determined by Confocal Microscope Olympus OLS 4000 Lext with a CCD camera.
