Single-Crystal Growth of Magnesium Orthovanadate, Mg₃(VO₄)₂, by the Optical Floating Zone Technique

Abstract

Magnesium orthovanadate crystals (< Φ 5 mm × L 55 mm) with a well-defined crystallographic orientation have been grown successfully in a four-mirror optical floating zone furnace. The crystals grow in the [010] direction. The transparent orange-brown crystals develop a predominant facet along the [20-1] during the crystal growth and cleave along the [20-1] and [100] directions.

EPR in Kagome Staircase Compound Mg2.997Co0.003V2O8

“…The investigated single crystals are orthorhombic (Cmca space group) with lattice parameters: a = 6.0495(8)Å, b = 11.426(2)Å, c = 8.303(1)Å [6]. This compound has the same crystal structure and very similar lattice parameters to the kagome staircase compound Co 3 V 2 O 8 .…”

Optical floating zone method growth and photoluminescence property of MgNb2O6 crystal

“…Such conditions allow for more stable and faster crystal growth [23][24][25][26][27][28]. Furthermore, the size of the grown crystals by the optical floating zone method is usually suitable for experimental measurements [29][30][31][32].…”

Vanadium and molybdenum disorder in M2.5VMoO8 (M = Mg, Mn, and Zn) determined with neutron powder diffraction and phase formation studies of Mg2.5+V1+2Mo1−2O8

“…Mixed metal oxides with vanadium and molybdenum in isolated MO 4 tetrahedra, such as Mg 3 (VO 4 ) 2 and MgMoO 4 , are active in the selective ODH of low molecular weight alkanes [1][2][3][4][5][6]. Mg 2.5 VMoO 8 , a mixed Mg-V-Mo metal oxide, has been shown to have selectivities and activities for the ODH of propane and butane that are similar to those of Mg 3 (VO 4 ) 2 [7,8].…”
