Compressibility profiles, or functions of solid fraction versus applied pressure, are used to provide insight into the fundamental mechanical behavior of powders during compaction. These functions, collected during compression (in-die) or post ejection (out-of-die), indicate the amount of pressure that a given powder formulation requires to be compressed to a given density or thickness. To take...

Ultrasound-assisted crystallization (sonocrystallization) was used to prepare a mixture of nanoand micrometer-sized crystals of the monoclinic form of paracetamol − a widely used analgesic known for its particularly problematic mechanical behavior under compression (i.e. poor tabletability). The nanoand microsized crystals yielded a powder which exhibits elastic moduli and bulk cohesions that a...

The compression of ceramic powders requires the addition of organic materials to insure tablet cohesion. For the compaction of formulated ceramic powders it is necessary to supply them energy. As a function of the formulation of ceramic powders, one can measure the specific energy acquired during the tablet compression. Recently, a technique used in powder metallurgy, High Velocity Compaction (...

Powder compaction technology has advanced significantly over the past decades and is considered as an alternative lower-cost process to machining, casting, stamping, forging and other similar metal-working technologies. Feedstock preparation is considered a vital step in producing parts through the powder route because any inhomogeneity within the powder mass would cause inhomogeneous density d...
