title: The packing characteristics of physical and formulated mixtures of oxytetracycline and lactose powders.
abstract: Measurements have been made of the tap densities and angles of internal flow of physically mixed and formulated mixtures of oxytetracycline and lactose powders. The differences between the two types of mixtures are ascribed to differences in the packing and surface morphologies of the particles.
