Structural characterization and colour of Ni3VxP2−xO8 (0 ≤ x ≤ 2) and Ni2VyP2−yO7 (0 ≤ y ≤ 2) materials

open access: yesResults in Physics, 2017
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.
