This paper is concerned with the mechanical behaviour of compacted ceramic green components of two alpha-SiC with different particle size-shape and purity with the purpose of evaluate the Drucker-Prager criterion in both material. Compaction pressures were between 60 and 100 MPa. The green compact were evaluated by two tests such as diametrical compression and uniaxial compression for different relative densities. These models are used both for die design as for parts design. The results show the different compression behaviour caused by the particles shape of each material.
