Ionic radii of ni
WebFigure 5 reports the solution enthalpies of MO (M = Fe, Co, Ni, Zn, Ca, Sr and Ba). The lowest solution enthalpy (0.01 eV) was calculated for Fe. Co, Zn and Ni also exhibit favourable solution enthalpies (<0.1 eV), suggesting that they are also promising candidates. This is because the ionic radii of those four dopants are close to each other. Web12 feb. 2024 · It is noteworthy that the lacunar HPAs can be obtained as soluble or insoluble salts, depending on the ionic radius of the metal cation that replaces the protons [29,30]. ... Conversely, the titration of Cu 2 SiW 12 O 40, Ni 2 SiW 12 O 40, and Co 2 SiW 12 O 40 solutions resulted in curves with two plateaus.

Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.
