Abstract
- 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 (HVC), has been studied to form ceramic compacts. This method brings special physical properties to tablets in terms of homogeneity compared to conventional uniaxial pressing. The properties of tablets prepared by the two processes are compared and discussed through a phenomenological model. [ABSTRACT FROM AUTHOR]
