Abstract
AbstractNine different kinds of U.S.P. grade talc samples were examined for variations in density, particle size, surface area, tendency of preferred orientation, and maximum ejection force. It was found that U.S.P. grade talcs varied in physical properties. The relationships between various physical properties of talc were analyzed using the Pearson's correlation of coefficient. The results suggested that the talc sample with a higher tendency of preferred orientation has closer bulk packing and talc with lower bulk density and higher surface area requires less peak force to break the tablet/die-wall adhesion.
