Interface-Assisted Synthesis of Single-Crystalline ScF3 Microtubes

Scandium fluoride (ScF3) microtubes with nanoscale wall thickness were for the first time successfully synthesized by an interface-assisted technique at the surface of a scandium nitrate aqueous solution without the addition of any surfactant as a result of interaction with hydrofluoric acid from the gaseous phase in only 30 min. X-ray diffraction analysis, scanning electron microscopy, helium ionic microscopy, transmission electron microscopy (TEM), and high-resolution TEM (HRTEM) were used to examine the morphology and crystal structure of ScF3 microtubes. The results show that the ScF3 microtube is single-crystalline and has a hexagonal structure. A hypothetical model of thin-walled microtube formation is proposed.

Large-scale synthesis of isotropic single-crystalline ScF 3 cubes by hydrothermal method

Scandium fluoride (ScF3) belongs to one of the rare compounds which exhibit isotropic negative thermal expansion. Here, a facile and environmentally friendly hydrothermal synthesis method has been presented. High-quality single-crystalline ScF3 cubes, with an average size of 200 nm, can be easily fabricated in a large scale. Sc(NO3) 3 and NH4HF2 were used as precursors. The as-prepared ScF3 demonstrates cubic symmetry (Pm-3 m), which was confirmed by X-ray diffraction and selected-area electron diffraction. Its uniform morphology and size were characterized by high-resolution transmission electron microscopy. Furthermore, thermal analysis was also performed in argon gas atmosphere to investigate its thermal stability.

Synthesis and characterization of new hydroxylammonium fluoromanganates and fluoroscandates

New hydroxylammonium fluorometallates of manganese and scandium, with the formulas (NH3OH)2MnF4and (NH3OH)3ScF6, were prepared by the reactions of hydroxylammonium fluoride with solutions of manganese or scandium in aqueous HF. (NH3OH)2MnF4crystallizes monoclinic, P21/c, the structure consisting of MnF6octahedra sharing four of its vertices, resulting in [MnF42-]nanionic layers perpendicular to a axis. (NH3OH)3ScF6crystallizes trigonal, R3c, and the structure is made up of isolated ScF6octahedra, stacked in columns along c axis and surrounded by a cylinder of hydroxylammonium cations. Both title compounds decompose during thermal analysis in several steps, yielding corresponding fluorides (MnF2and ScF3) at temperatures between 300 and 400 °C and oxides/oxofluorides at higher temperatures.
