Abstract
The present study addresses the application of microwave (MW) energy for melting lithium phosphate glass. A
comparative analysis of the properties is presented with glasses melted in conventional resistance heating adopting standard methods of characterization. The density of the glass was found less in MW heating. The glass transition temperature was recorded as 3–10◦C lower in MW prepared glass than in conventional glass. Micro-hardness is found to be improved in case of MW heating. Maximum forward power was recorded less than 2 kW with an average power ∼1kW during melting of 40g glass in MW furnace. MW forward and reflected power measured during melting in the MW cavity was elaborated. Total melting time was within 2h 30 min in MW heating, whereas it was 6–7 h in resistive heating. Total power consumed was ∼5kWh in MW heating and ∼14kWh in resistance heating.
