The investigations are dedicate to determination of possible hereditaly anisotropy of selfdiffusion in the metal melts. The building of the melt Zn is comparing with the frozen structures of the samples. In this purpose the sample selection before solidification was made with using of the effect of separation of liquid on the structural fragments. The availability in melts the layer fractals and the free volume like deposit of pores that have cuts is established. The building of the boiling melt is characterized by colloids. The internal volume of colloids contain the strip compositional motive. The free volume of the frozen structure of boiling melt distribute among boundaries of colloids. On the base of data the choice of orientation parameters of monocrystalls of Zn are substans for the investigation of the processes of selfdiffusion in its melts in conditions of microgravitation.
