Structural characterization of Ni3VxP2−xO8 (0 ≤ x ≤ 2) and Ni2VyP2−yO7 (0 ≤ y ≤ 2) compositions was made and colour parameters of these materials measured. Ni(II) diphosphate and divanadate crystalline phases are not stables at high temperature. Solid solutions in Ni3P2O8 and Ni3V2O8 are obtained by incorporation of V(V) in Ni orthophosphate and P(V) in Ni orthovanadate structures. Solid solutions with Ni3V2O8 structure are formed in a greater compositional interval than solid solutions with Ni3P2O8 structure. These materials might be used as ceramic pigments because of its thermal and chemical stability. Tan brown colorations were obtained in glazed tiles when the fired compositions were 4% weight enamelled with a commercial glaze. Keywords: Phosphates, Vanadates, Nickel, Structure, Solid solutions, Colour |
