The Use of Tableting Indices to Study the Compaction Properties of Powders

AbstractTableting indices are employed to investigate some compression properties of a binary mixture of a direct compression excipient, calcium sulfate, and a tablet lubricant, magnesium stearate. The technique involved modifications of previously described equipment used to acquire and quantitate the bonding index, brittle fracture index, and strain index. The present paper describes the significant modifications and contributions made on equipment, and presents some results obtained for some binary mixtures of powders.
