Thulium Carbonate Hydrate Powder Description
Thulium Carbonate Hydrate Powder
Tm2(CO3)3·xH2O is a rare earth compound
that typically appears as a light green powder. It is sparingly soluble in
water but readily reacts with mineral acids, releasing carbon dioxide and
forming the corresponding thulium salts. The compound is thermally unstable and
decomposes upon heating to produce thulium oxide (Tm₂O₃), a valuable material
used in electronics and optical applications. This decomposition generally begins
above 300°C, making thermal treatment a common method for converting the
carbonate into the oxide form.
Thulium Carbonate Hydrate Powder is
chemically stable when stored in a dry, cool environment, but it is mildly
hygroscopic and may absorb atmospheric moisture over time, potentially altering
its physical properties. It does not pose significant hazards under normal
laboratory handling, but should be treated with care to avoid inhalation of
dust or prolonged contact with skin and eyes.
The presence of thulium imparts
unique luminescent and magnetic characteristics to this compound, which are
useful in applications such as phosphors for display technologies, laser
materials, and specialized ceramics. Additionally, it serves as a convenient
intermediate in the preparation of high-purity thulium compounds for research,
industrial processes, and advanced materials engineering.
Thulium Carbonate Hydrate Powder Applications
1. Precursor for Thulium Oxide (Tm₂O₃): Thermal
decomposition of Thulium Carbonate Hydrate Powder yields thulium oxide, which
is widely used in lasers, ceramics, and electronic components.
2. Laser Materials: Used in the production of thulium-doped
laser crystals and fibers for solid-state and medical lasers, particularly in
the infrared range (~2 μm).
3. Phosphors and Luminescent Materials: Employed in the
synthesis of blue-emitting phosphors for display and lighting technologies.
4. Advanced Ceramics: Acts as a dopant in high-performance
ceramics to enhance thermal, magnetic, or optical properties.
5. Glass and Optical Coatings: Used to modify the refractive
index and transmission properties of specialty glass and coatings.
6. Research and Development: Utilized in academic and
industrial research as a source of thulium in the preparation of other thulium
compounds or materials.

1. Common Preparation Methods
Thulium Carbonate Hydrate Powder is typically prepared via a
precipitation reaction between a soluble thulium salt and a carbonate source.
In a standard laboratory procedure, thulium nitrate (Tm(NO₃)₃) or thulium
chloride (TmCl₃) is first dissolved in deionized water to form a clear, light
green solution. An aqueous solution of sodium carbonate (Na₂CO₃) or ammonium
carbonate ((NH₄)₂CO₃) is then slowly added to the thulium solution under
continuous stirring. As the carbonate is introduced, a pale green precipitate of
Thulium Carbonate Hydrate Powder forms immediately. The reaction proceeds as
follows (using thulium nitrate as an example):
2Tm(NO₃)₃ + 3Na₂CO₃ → Tm₂(CO₃)₃↓
+ 6NaNO₃.
The resulting precipitate is aged for complete reaction,
then separated by filtration or centrifugation. It is washed several times with
deionized water to remove residual byproducts such as sodium or ammonium salts.
Finally, the product is dried at low temperature (typically 60–80°C) to yield
pure Thulium Carbonate Hydrate Powder. This method produces a high-purity
material suitable for use in ceramics, optical components, and rare earth
synthesis.
