Influence of temperature on synthesis process by spontaneous crystallization of nickel chromite NiCr2O4 with structure of spinel is investigated. Steady formation of chromonickel spinel in a temperature interval of 900-1050 °C is established. X-ray diffraction characteristics (parameters of an elementary cell, density), morphological features, particle size distribution of chromite of nickel are defined.
nickel chromite, chromonickel spinel, infrared ranges, morphology of crystals, simple forms of an facet octahedron and tetragontrioctahedron
