Flow Property: (1) The flow properties of solids have great impact on the tableting processes since their manufacturing require the flow of powder from a storage container to tablet dies. (2) Weight and content uniformity are also dependent on flow […]
Optical Microscopy: Equivalent diameter: It is used to determine projected area diameter, Feret’s diameter and Martin’s diameter. Range of analysis: 1 μm to about 100 μm. Methodology: Firstly, the powdered substance is placed over the stage and obseved through the […]
DERIVED PROPERTIES OF POWDERS: There are numerous derived properties that are based on fundamental properties. Those with particular relevance to pharmacy are discussed here. Packing geometry Porosity Density Bulkiness Flow property Packing Geometry: A set of particles can be filled […]
Density (Ƿ): Density is defined as weight per unit volume. Based on the types of volume defined, the corresponding ‘density’ may be proposed. Table 1 – Types of densities Density Dełnition Formula Determination Comment Bulk(Ƿb) Mass divided by bulk volume […]
