Usage

Uses

Scandium Acetate is applied in optical coating, catalyst, electronic ceramics and laser industry. Acetates are excellent precursors for production of ultra high purity compounds, catalysts, and nanoscale materials. The main application of Scandium by weight is in Scandium-Aluminium alloys for minor aerospace industry components. Dentists use Erbium, Chromium: Yttrium-Scandium-Gallium Garnet (Er,Cr:YSGG) lasers for cavity preparation and in endodontics.

Preparation, morphology, and luminescent properties of europium-doped nanodispersed scandium sesquioxide

Scandium sesquioxide-based solid solutions of composition Sc 2 - 2x Eu2x O3 (0.005 ≤ x ≤ 0.05) were prepared by thermolysis of Sc1 - x Eu x (CH 3COO)3 and by reacting mixtures of scandium and europium nitrates with ethylene glycol. Thermal decomposition of Sc1 - x Eu x (CH3COO)3 was found to yield Sc 2 - 2x Eu2x O3 with the shapes of aggregates atypical of the cubic structure of this oxide, and the reaction products of scandium and europium nitrates were found to have a loose spongelike structure. A spectroscopic study showed that Sc2 - 2x Eu2x O 3 and Sc1 - x Eu x (CH3COO) 3 are potential luminescent materials active in the visible spectral region. The tervalent europium in the Sc2 - 2x Eu2x O 3 structure is the source of strong red emission (5 D 0 → 7 F 2) and can be used in fluorescent lamps, colored lightning, and optoelectronic devices.

Crystal Structure of Sc(CH3COO)3, a Metal(III) Acetate with a Chain Structure

Sc(acO)3 was obtained from Sc2O3 and (CH3CO)2O or from Sc2(CO3)3 and acetic acid.Recrystallization in water yields hexagonal columns of anhydrous Sc(acO)3.It crystallizes in the space group P63/mcm with the lattice constants a = 791.1(3) pm, c = 886.6(7) pm and z = 2.Sc(acO)3 exhibits a polymeric structure with a linear chain of metal atoms which are connected in each case by three bridging acetato groups.For the Sc atoms results a sixfold coordination in the form of a compressed octahedron with the symmetry D3d and with distances Sc-O = 208.4 pm.The columns of polymeric Sc(acO)3 are arranged like in an ideal hexagonal close packing of cylindrical rods. - Key words: Scandium(III) Acetate, Synthesis, Crystal Structure, Chain Structure
