Influence of temperature on the compaction and the mechanical strength of an organicpowder
Résumé
Classical works made on powder compaction have been developing studies of parameters like the maximum pressure reached, the punch velocity, the duration of isobaric stage, on tablets properties. But the influence of temperature during the compression has been neglected in most cases. Now, most of pharmaceutical and chemical products, in particular organic products, are sensitive to temperature. In this work, the role of temperature on the compressibility of an organic powder commonly used in the industry has been examined. The consequences on the structure and on the mechanical behaviour of the tablets have been studied. The evolution of the porosity, the tablet strength and the fracture aspects have been followed and then analysed during and after the compression.
