✦ Synopsis

The usefulness of the Jenike-type shear cell and associated procedure for the characterization of some powder bed properties has been established by others. An attempt to use a simpler procedure and a different shear cell and thereby to reduce the quantity of powder required is described. The yield loci obtained are very nearly linear. Multiple-regression analysis is used to obtain characteristic constants from the data for the family of yield loci. Examples of the data obtained for various pharmaceutical powders are presented.
