Notable Research Contribution

  • Developed Energy efficient, cost effective method for melting of bulk glasses (50-500g) by microwave heating. Demonstrated 50-70% energy saving and also shorter processing time in microwave melting of glass in compare to conventional resistance heating. Demonstrated less evaporation loss of ingredients and less contamination from crucible wall in microwave heating. Demonstrated capability of microwave heating to minimize OH content in glass
  • Demonstrated more Fe+2 retention in glass in air atmosphere in microwave heating and thereby developed heat absorbing properties in glass ( unlike reducing atmosphere essential in conventional heating).
  • Demonstrated a process of developing colour glass utilizing toxic waste (tannery solid waste, arsenic contaminated sludge etc). Developed a glass foam utilizing land filled glass-waste.
  • Estimation of the Fe2+oxidation state in glass with spectrophotometric methods developing ferrozine.
