All Technologies

The sodium metal is a raw material for pharmaceutical uses and is also used as a coolant in Fast Breeder Reactor (FBR). No commercial production/ technology is presently available in India, hence total Indian demand is met by import only. CSIR-NML has successfully designed, fabricated, and operated 500A closed sodium cell and produced sodium metal by molten salt electrolysis of sodium chloride. Based on the expertise a 3000A pilot-scale closed sodium cell was designed, fabricated, and demonstrated at the premises of M/s Sree Rayalseema Hi-Strength Hypo Ltd. (M/s SRHHL), Kurnool, AP. The pilot plant was operated successfully for at least a month and produced a significant amount of sodium metal. The purity of the metal was between 99.9 to 99.83% and the cell efficiency was about 83%. The indigenously developed cell design was successfully proven. Based on the success of the pilot-scale operation the commercialization/ industrialization of sodium metal production technology is under progress at the premises of M/s SRHHL, Kurnool up to a capacity of 144000A which includes 12000A of 12 cells aiming to produce 700MT per annum.

Indigenous technology to produce sodium metal first time in India, The electrolytic cell is designed in such a way that it can produce up to 99.9% pure sodium metal with a cell efficiency of 83%, The cell was designed to operate continuously for a longer time and its capacity was 3000A, The sodium metal can be used for making sodium hydride, which has large pharmaceutical uses, Commercialization/ industrialization is under progress.
