Scandium Acetate Hydrate Powder Description
Scandium Acetate Hydrate Powder is a white, crystalline rare earth compound composed of
scandium ions coordinated with three acetate ligands. It is typically supplied
as a hygroscopic powder that is readily soluble in water and other polar
solvents such as ethanol and methanol. This high solubility makes it especially
useful for solution-based synthesis techniques, including sol-gel processing
and thin-film deposition.
Chemically, scandium acetate is
stable under ambient conditions if kept dry, but it can slowly absorb moisture
from the air. When heated, it decomposes in a multi-step process, first losing
acetic acid and then converting to scandium oxide (Sc₂O₃), a material of
interest in solid-state devices, fuel cells, and high-performance ceramics. The
thermal decomposition typically occurs above 200°C and is often used
intentionally in the preparation of pure oxide films or powders.
Scandium ions impart beneficial
properties such as high melting point, low density, and improved strength when
used in alloy or ceramic formulations. As a result, scandium acetate is widely
used as a precursor in the synthesis of advanced functional materials,
catalysts, and phosphors. It also finds roles in research applications
involving coordination chemistry and in doping systems for optical or electronic
materials.
Scandium Acetate Hydrate Powder Applications
1. Advanced Ceramics: Used as a dopant or precursor in
high-performance ceramics to improve thermal stability, mechanical strength,
and ionic conductivity.
2. Scandium Oxide Production: Serves as a soluble precursor
for producing scandium oxide (Sc₂O₃), which is used in solid oxide fuel cells
(SOFCs), optical coatings, and electronic materials.
3. Catalysis: Acts as a component or precursor in
homogeneous and heterogeneous catalysts, particularly in organic synthesis and
polymerization reactions.
4. Optical and Electronic Materials: Used in the preparation
of scandium-doped materials for lasers, phosphors, and electronic devices,
often to enhance luminescent or conductive properties.
5. Research and Development: Commonly used in academic and
industrial research to prepare other scandium compounds or study scandium's
coordination chemistry.
6. Metal Alloy Additive (Indirect Use): Though not directly
used in alloys, scandium acetate may be part of processing routes for
introducing scandium into aluminum and other alloys for aerospace and
lightweight structural materials.

1. Common Preparation Methods
Scandium Acetate (Sc(O₂C₂H₃)₃) is typically synthesized by
reacting scandium oxide (Sc₂O₃) with glacial acetic acid under controlled
heating conditions. In a common procedure, scandium oxide is slowly added to
excess acetic acid while stirring and heating the mixture to around 80–100°C.
The oxide gradually dissolves, forming a clear solution of scandium acetate as
the reaction proceeds according to the equation: Sc₂O₃ + 6CH₃COOH → 2Sc(CH₃COO)₃ + 3H₂O. Once the
reaction is complete, the solution is filtered to remove any unreacted solids
and then concentrated by evaporation under reduced pressure. Upon cooling or
further drying, scandium acetate precipitates out as a white crystalline solid
or powder. The final product is collected and dried under vacuum or in a
desiccator to minimize moisture absorption. This method yields high-purity
scandium acetate suitable for use in ceramic processing, catalysis, and
material synthesis.
