Research Interest:

Material Science & Technology with special interest on:

  • Glass Chemistry & Special Glass Development
  • Ultra-low expansion glass ceramics and low expansion lithium alumino-silicate ceramics
  • Specialty Optical Glass, Radiation Shielding Window (RSW) Glass and Specialty Borosilicate Glass Bead for Immobilization of High Level Radioactive Nuclear Waste
    • Notable Research Contributions

       a) Professional Experience:

      During his tenure of nearly 31 years at CSIR-CGCRI, he played a very key role in research and developmental work in the field of Glass Science & Technology. His current research activities are in the area of high density Radiation Shielding Window (RSW) Glass for Radiation Protection in Nuclear Hot Cell and Specialty Borosilicate Glass Frit / Bead for Nuclear Waste Immobilization where in Technology Development and Commercialization have been the main focus. While the Radiation Shielding Window Glass is being produced in pilot scale at CGCRI for catering into the need of Department of Atomic Energy (DAE), the technology of specialty glass beads has been successfully transferred to an industrial partner for commercial production and supply to DAE’s units. He is the key person for indigenous production of RSW glass and borosilicate glass bead for nuclear waste immobilization in our country. He has taken an ambitious target to produce RSW glass in specialty refractory crucible instead of platinum crucible for DAE.

      The activities of the undersigned resulted in development of appropriate technology, development of product (strategic material), generation of knowledge base in the form of technical papers, patents, reports etc. He has published 15 papers in national and international journals and conference proceedings and filed 4 patents in India. He has also prepared more than 15reports / documents for restricted circulation.

      b) Contributions:

      Optical glass Technology, Specialty Optical Glass, Radiation Shielding Window (RSW) Glass and Specialty Borosilicate Glass Bead for Immobilization of High Level Radioactive Nuclear Waste, Ultra Low Expansion Glass-Ceramics, Low Expansion Ceramics

      c) Current Research Activities are in the areas of:

    • Development of specialty glass in nuclear hot cell application,
    • Development of specialty borosilicate glass frit/bead with for application in nuclear waste fixation
    • Technology transfer and commercialization of the technology.
