New continuous solid solution in the Zn2InV3O11–Mg2InV3O11 system

Effect of Magnesium Substitution on Dielectric Constant of Zn2-xMgxInV3O11 (x = 0.0, 0.4, 1.6) Solid Solutions

“…A natural source of these traps can be grain-boundaries with depletion layers of adjacent grains, as it has been observed for ZnO varistors [8], Nb 2 VSbO 10 ceramics [9] and some copper/cobalt and rare-earth metal tungstates [10] as well as reported for (Co,Mn)Pr 2 W 2 O 10 [11]. The above-mentioned dielectric properties could be interpreted as related to the relaxation process like with Maxwell-Wagner [12] or Jonscher [13], because the solid-state density of the phases under study decreased with increasing magnesium content [6]. The reduction in this density was a consequence of the reduction in the number of vanadium ions with mixed valence.…”

“…Vanadates (V) of divalent metals exhibiting the presence of isolated VO 4 tetrahedra in their structure display a good selectivity and high activity as catalysts for the oxidation processes of light hydrocarbons or as cathode materials in high-energy cells. Among phases recently obtained there are some compound which are formed in the systems: MO-Fe 2 O 3 /In 2 O 3 -V 2 O 5 , where M = Mg, Zn, Co, Ni, Pb, Ba, Sr [1][2][3][4][5][6]. The double vanadates of the general formula M II 2…”

“…Research conducted in the quaternary oxide system ZnO-MgO- while the values of the unit cell parameter c decreased with increase of magnesium content. The solid-state density values obtained experimentally and calculated on the basis of X-ray diffraction (XRD) data decreased as a function of the degree of Mg 2+ ions incorporation in the crystal lattice of Zn 2 InV 3 O 11 [6].…”

Dipole Relaxation in Semiconducting Zn2−xMgxInV3O11 Materials (Where x = 0.0, 0.4, 1.0, 1.6, and 2.0)

“…Its unit cell parameters a and b increased, while the unit cell parameter c decreased with an increasing magnesium content [10]. The solid-state density values obtained experimentally (d exp ) and calculated (d cal ) based on X-ray diffraction (XRD) data decreased as a function of the degree of Mg 2+ ions' incorporation in the crystal lattice of Zn 2 InV 3 O 11 [10], where a good agreement was shown between d exp and d cal . The level of porosity of p l ≈ 1.67% determined using the formula p l = (1 − d exp /d cal ) did not depend on the magnesium content x.…”

“…A solid solution of a Zn 2−x Mg x InV 3 O 11 composition was found to form in the Zn 2 InV 3 O 11 -Mg 2 InV 3 O 11 system [10]. The phases with x = 0.0, 0.4, 1.0, 1.6, and 2.0 were obtained using solid-state reactions.…”
