Abstract
Abstract
Air permeability and liquid penetration of tablets of sucrose and lactose have been measured. The tablets had been compressed over a wide pressure range from granules which varied in bulk density, size and strength. The degree to which inter- and intra-granular pore structure within the tablet was sustained varied with these properties; low pressure, high density, high strength and large size promoting a more open but less uniform structure. Such structures allowed rapid penetration of liquid through a coarse pore network which isolated a large fraction of the total pore space. Thus tablets of high permeability gave low final degrees of saturation whereas less permeable tablets became fully saturated.
