had no direct industrial application had certain amount of scientific
curiosity & challenge.
Preliminary experiments were done in Fritsch Pulverisette Mill available in
the institute that time (in 120 hr, very small Fe3C peak feasible) did not

Crude prototype was developed in 6 months and in 40 hr milled powderwas analyzed using XRay Diffraction: moment of triumph.
