Humidity, dustability or angle of repose may have relation to the loss in weight on dividingand packaging of powder. The above physical Properties and factors were examined with powders in three forms such as fluffy powder, fine granule and granule. It seems that the loss in weight on dividing of powder changes in proportion to the mixing ratio and the angle of repose, and in inverse proportion to the dispersibility. But the loss of weight may depend more largely on physical factors other than the angle of repose and dispersibility, because the rate of weight loss is different by the form and quality of powder.
