Overview

The Central Glass and Ceramic Research Institute is the premier research institute of its kind in the country and involved in the research and development (R & D) in the area of glass science and technology. Since the inception of this Institute, Glass Division has been serving the country with a mandate to develop specialty glasses for civil and advance technology applications as well as extending services to glass industry in lab scale trial glass meltings, testing and quality assurance of their products.

In this direction, Glass Division has developed various glasses and glass-ceramics namely radiophotoluminescent (RPL) glasses, filter glasses, colored signal glasses, new generation lanthanum bearing optical glasses, rare-earth doped luminescent glasses, micronutrient glass fertilizers, graded refractive index (GRIN) glasses, fullerene (C60) doped glasses, tellurite glasses, fluorophosphate glasses, transparent nanocrystalline glass-ceramics, machineable glass-ceramics, honey-comb cordierite glass-ceramics, etc. for different applications. Besides these, very recently, it has developed lead-free environmentally friendly, low cost glass powders and pastes for new generation of Plasma Display Panel (PDP) with Industry– Institutes collaboration.

Currently, various R & D activities on glasses and glass-ceramics are being pursued such as metal-glass hybrid nanocomposites, oxyfluoride glass-ceramics, rare earth doped nanocrystalline nonlinear optical glass-ceramics, semiconductor glass-ceramics, chalcogenide glass, fluoride glass, etc. for use in solar cell, light emitting dodes (LEDs), energy storage, infrared optics, photonic and optoelectronic devices. In addition to the above, alternate method of glass melting using microwave heating has been demonstrated to prepare bulk glasses consuming substantial less electrical energy and time.
