Beige materials for the ceramic industry: AlxVyFe1-xP1-yO4 (0.0 ≤ x ≤ 0.3, 0.0 ≤ y ≤ 0.1) solid solutions
Elsevier (2019-05)AlxVyFe1-xP1-yO4 (0.0 ≤ x ≤ 0.3, 0.0 ≤ y ≤ 0.1) compositions were synthesized via the chemical co-precipitation method. At 500 °C, α-FePO4 berlinite crystallizes together with FePO4 tridymite, Fe(III) occupying tetrahedral ... -
Co2P2O7‐Ni2P2O7 solid solutions: Structural characterization and color
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 ... -
Experimental and theoretical study of SbPO4 under compression
American Chemical Society (2019-12-26)SbPO4 is a complex monoclinic layered material characterized by a strong activity of the nonbonding lone electron pair (LEP) of Sb. The strong cation LEP leads to the formation of layers piled up along the a axis and linked ... -
Influence of the structure of CrPO4 on the formation of CrVxP1−xO4 solid solutions and their colour
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 ...
