AUTHORS have used a new way for measuring bulk volume based on the image (pixel) analysis named as Light Table Imaging (LTI), and subsequently bulk densities and porosities. Authors lately found that there was a slight error in calibrating the scale (known distance) to pixel measurement and understand the need to communicate the error and subsequent corrections. After correcting the calibration scale appropriately, the corresponding corrections have been implemented to evaluate the values of bulk volume, bulk density, porosity, sintering ratio and further kinetic parameters for all the pellets used in the study. The corrections have only changes the absolute values and does not affected or changed the understanding, outcome and conclusions of the study. Therefore, it is requested to incorporate the changes – Figures and Table by the corrected ones as mentioned below.
