Synthesis and characterization of mullite‐type Sn(Cr1-xVx)BO4: Structural, vibrational, magnetic, and thermal properties
Abstract
<jats:title>Abstract</jats:title><jats:p>The susceptibility of either oxidation into Sn(IV) or disproportionation into Sn(IV) and Sn(0) limits the study of metal tin‐(II)‐borate ceramics. We report mullite‐type SnCrBO<jats:sub>4</jats:sub> and SnVBO<jats:sub>4</jats:sub> synthesized in sealed quartz tubes by conventional solid‐state method. X‐ray powder diffraction data Rietveld refinements confirm that both compounds are isostructural to Pb<jats:italic>M</jats:italic>BO<jats:sub>4</jats:sub> phases for <jats:italic>M</jats:italic> = Al, Ga, Cr, Mn, and Fe. The end‐members show a complete miscibility within the Sn(Cr<jats:sub>1−</jats:sub><jats:italic><jats:sub>x</jats:sub></jats:italic>V<jats:italic><jats:sub>x</jats:sub></jats:italic>)BO<jats:sub>4</jats:sub> solid solution. Both the microstructural (average crystallite size, microstrain, and degree of crystallinity) and crystal structural (metric parameters, bond lengths, polyhedral volume, and polyhedral distortion) parameters are observed with respect to the compositional <jats:italic>x</jats:italic>‐value. The stereochemical activity of the 5 s<jats:sup>2</jats:sup> lone electron pairs of Sn<jats:sup>2+</jats:sup> cations has been measured by using the Wang–Liebau eccentricity parameter. The structural features are complemented by <jats:sup>119</jats:sup>Sn Mössbauer, Raman, and Fourier‐transformed infrared spectroscopy. The <jats:sup>119</jats:sup>Sn Mössbauer isomer shifts and the quadrupole splitting values confirm the SnO<jats:sub>4</jats:sub> coordination and an Sn(II) valence state. The electronic band gap has been calculated from the UV/Vis diffuse reflectance spectra, which slightly increases with successive decrease of the cationic radius from V to Cr. Temperature‐dependent inverse DC magnetic susceptibility suggests that SnCrBO<jats:sub>4</jats:sub> and SnVBO<jats:sub>4</jats:sub> are antiferromagnetic and ferromagnetic (FM) with a Néel temperature of 17.2(1) K and a Curie temperature of 29.8(1) K, respectively. Alike the end‐member SnVBO<jats:sub>4</jats:sub>, Sn(Cr<jats:sub>0.5</jats:sub>V<jats:sub>0.5</jats:sub>)BO<jats:sub>4</jats:sub> is also found to be a rare FM insulator. The thermal stability decreases with increasing vanadium content in the solid solution.</jats:p>
