    • openAccess   Ceramic pigments from CoxNi3-xP2O8 (0 ≤ x ≤ 3) solid solutions 

      Tena, M. A.; Mendoza, Rafael; Trobajo-Fernández, María del Camino; García, José R.; Garcia-Granda, Santiago Elsevier (2021-07-17)
      CoxNi3-xP2O8 (0 ≤ x ≤ 3) solid solutions were synthesized via the chemical co-precipitation method. Variation of unit cell parameters and interatomic distances indicated that these solid solutions with the Ni3P2O8 structure ...

    • closedAccess   Characterization of yellow and red inorganic pigments from Mg0.5Cu1.5VxP2−xO7 (0 ≤x≤2) solid solutions 

      Tena, M. A.; Mendoza, Rafael; Martínez, David; Trobajo-Fernández, María del Camino; García, José R.; Garcia-Granda, Santiago Springer (2020)
      The structural characterization of Mg0.5Cu1.5VxP2−xO7 (0.0 ≤x≤2.0) compositions was performed and the colour parameters of these materials measured. Solid solutions in the α-Cu2P2O7, β-Cu2P2O7 and β-Cu2V2O7 structures were ...

    • closedAccess   Co2P2O7‐Ni2P2O7 solid solutions: Structural characterization and color 

      Tena, M. A.; Mendoza, Rafael; Trobajo-Fernández, María del Camino; Garcia-Granda, Santiago Wiley (2018-10)
      NH4[Co1−yNiyPO4]·H2O (0 ≤ y ≤ 1) single crystals were fired to prepare Co2−xNixP2O7 0 ≤ x ≤ 2 solid solutions between 800 and 1200°C. The structure of these solid solutions is α‐M2P2O7 (M = Co, Ni). The contraction of the ...

    • openAccess   Cobalt Minimisation in Violet Co3P2O8 Pigment 

      Tena, M. A.; Mendoza, Rafael; Trobajo-Fernández, María del Camino; Garcia-Granda, Santiago MDPI (2022-01-31)
      This study considers the limitations of cobalt violet orthophosphate, Co3P2O8, in the ceramic industry due to its large amount of cobalt. MgxCo3−xP2O8 (0 ≤ x ≤ 3) solid solutions with the stable Co3P2O8 structure were ...

    • closedAccess   Influence of the structure of CrPO4 on the formation of CrVxP1−xO4 solid solutions and their colour 

      Tena, M. A.; Mendoza, Rafael; García, José R.; Garcia-Granda, Santiago Elsevier (2017-10-01)
      CrVxP1-xO4 (0 <= x <= 1) compositions were synthesized via the chemical co-precipitation method. At 600 degrees C, the detected crystalline phase is monoclinic CrVO4 when x >= 0.7. At 800 degrees C, two isostructural phases ...

    • openAccess   Structural characterization and colour of Ni3−xCuxP2O8 (0 ≤ x ≤ 3) materials 

      Tena, M. A.; Mendoza, Rafael; Trobajo-Fernández, María del Camino; García, José R.; Garcia-Granda, Santiago Springer (2021)
      The structural characterization of Ni3−xCuxP2O8 (0.0 ≤ x ≤ 3.0) compositions was performed and the colour parameters of these materials measured. Solid solutions with Ni3P2O8, Ni2CuP2O8 and Cu3P2O8 structures were ...

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

      Tena, M. A.; Mendoza, Rafael; García, José R.; Garcia-Granda, Santiago Elsevier (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 ...
