Abstract

Glass comprising of P2O5-Al2O3-Na2O-ZnO is melted in microwave (MW) heating as an alternate energy efficient heating method. Properties of glasses obtained from MW heating are compared with that of glasses prepared adopting resistive heating. Glass transition temperature (T-g) in MW melted glass is found similar to 15-20 degrees C lower compared to the glass prepared in resistance furnace. XPS O1s spectra indicate less non-bridging oxygen (NBO) formation in glass obtained from MW melting. This may be due to less evaporation as well as less leaching of alumina from crucible wall during melting. Photoluminescence spectra of Eu3+-doped glass indicate higher asymmetric ratio in the conventional glass. MW melting requires 2 h 20 min, whereas it is similar to 6 h in resistive heating. Comparison of power consumption analysis depicts maximum MW forward power < 1.5 kW with similar to 1 kW average power during melting of glass. Maximum power in resistive heating furnace is recorded 4 kW for identical melting.
