A process for the preparation of double potassium-nickel (II) diphosphate comprises the use of melt of mechanical mixture of polycrystalline substances. The mechanical mixture of KPOand NHHPOis grounded to homogeneous state, baked for 1 hour at temperature of 850 °C. The melt is saturated at mixing with potassium fluoride and held at temperature of 850 °C for 1 hour. It is saturated with nickel (II) oxide and held, mixed and crystallized by the decreasing of temperature from 900 °C to 700 °C for 24 hours. The produced monocrystals of double diphosphate of KNiPOare washed and dried at the room temperature.
