The vapor phase over zinc pyrovanadate is found to contain the complex ion . A model for the formation of lattice defects in Zn2V2O7 during heating is proposed. The explosive phase transition during cooling is shown to be associated with the formation of the vacancy complex [vacancy-] ZnVO3 Полный текст |
