Abstract
Barium borosilicate glass having composition in wt.% (46.5) SiO2, (26.5) B2O3, (16.5) Na2O (10.5) BaO was melted at 1473K in a microwave furnace and also in a conventional resistance heating furnace. A comparative study of the properties of both the glasses was conducted by adopting standard methods of characterisation. Glass transition temperature was recorded as 825K and 829K for glass samples prepared in microwave and conventional heating respectively. Low evaporation of volatile component was observed in microwave prepared glass which leads to less density of glass in comparison with glass prepared in conventional method. ‘Self stirring’ effect in microwave prepared glass sample was observed in annealed glass obtained without pouring it into preheated mold. Identical structure and optical transmission were found in both the glasses. OH content was estimated low in glass melted in microwave heating over conventional heating. Microwave heating can be a potential alternative method of preparing glass with substantial reduction of energy and processing time.
