[Deformation phenomena occurring during compression. II].
Compressed forms were prepared from sodium chloride of given granule size with mildly concave punches applying 4, 12 and 20 kN pressing force. Pressing was regulated in order to get maximum pressing force effect for 0.1 s, 30 s and 60 s. Textures of side of compressed forms as well as edge and middle of surface of compressed forms were investigated by scanning electron microscope. Photos made with different enlargement have proved that secondary structural changes have begun (colour changes, new crystals have come to being etc.) on side stronger but also well observable on surface of compressed forms which in function of pressing force and that of time of pressing force effect have increased and grown considerably.
