| Abstract |
| Quantitative estimation of particle size of crystalline materials is
commonly made by, among others, scanning electron microscopy
(SEM)/transmission electron microscopy (TEM), X-ray diffraction
(XRD) etc. In this paper, the newly employed Mossbauer spectroscopic
technique has been evaluated with respect to other methods.
The premise employed involves the significant Ielationships of particle
size with (a) relaxation time, showing exponential relationship,
(b) hyperfine field and recoil-free fraction, showing cortesponding
linear decrease, and (c) line width, showing inverse relationship. |
