Abstract Compaction of ceramic materials is an important technological operation. From the variety of existing methods of formation is necessary to assign static and isostatic pressing, in which the compact is applied to the constant pressure to provide the desired density prevalence of the volume of the material. To increase the density also dynamic compression techniques are used, especially using a pulsed electromagnetic field (PEF). Compaction powder composition is carried out by crimping it in the rigid matrix, or a deformable metal shell. However, this method does not allow to achieve uniformity and high density properties. Therefore combined methods combining static and pulsed magnetic impulse compaction are attractive. The process for compacting powdered material prior static compaction step in this case can be considered as the process of particle glide relative to each other and the deformation of particle contact parts. With the increasing compaction of the pressure, the density of the agglomerates increases due to the better packing of the particles and increased their contact surface. Impulse loading allows to improve these processes. When there is a compaction in a rigid matrix processes static and pulse loading it is advisable to to alternate with a gradual pressure increase.
