摘要：
Within the frame of the phenomenological theory of second-order phase transitions for thermodynamic potential which is invariant with respct to group of transformations of C-3V (3m), conditions of destroy of tetra(c)ritical point were obtained. The phase diagram of such destroy corresponding to experimentally received diagram of system MnTi2-xVxO4 was considered in details. Conditions of occurrence of tricritical and triple points were formulated. The equations for calculation of their coordinates are given.
