STRUCTURAL PHASE TRANSFORMATION IN Cu1,80Ni0,2S CRYSTAL

Abstract

The structural phase transformation of the composition Cu1,80Ni0,2S in the solid solution was
synthesized and investigated by the method of DTA and x-ray diffraction. It was determined that the
achieved crystal has rhombic lattice which is transferred into hexagonal form at the temperature
379K and in its turn the hexagonal modification is turned into the cubic form at 1079K. This transfer concerns to the enantiotropic type.
Keywords: polymorphism, modification, enantiotropic, transformation
