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.
  • Rate of Volatilization loss of B2O3 could be minimized 15-20%  less in Microwave heating ( Than in conventional heating)
  • Many specialty glasses and glass ceramic blocks (i.e. radiation shelding window glass, ultra low glass ceramic and Nd-doped Phosphate based LASER glass) have been produced in pilot scale. Operation and commissioning of pilot plant for production of special glass and glass ceramic. Utility design for the pilot plant. Designing Platinum crucible and stirrer for indigenous development LASER glass
  • Developed rare earth doped oxy-fluoride glass-ceramics containing fluoride nano-crystals (Eu doped NaYF4) of low phonon energy.
