Yttrium Sulfate Octahydrate

Yttrium Sulfate Octahydrate powder is a white crystalline powder with the chemical formula of Y2(SO4)3.8H2O, soluble in water and acidic, which has applications in the fields of material science, chemical analysis and catalysts.

Properties

Chemical formula: Y2(SO4)3.8H2O

Molecular weight: 610.11

CAS No.: 7446-33-5

Appearance: white crystalline powder, white color, no obvious impurities or off-color.

Solubility: soluble in water, its aqueous solution is acidic. The solubility in water increases with the increase of temperature, and the dissolution process will absorb heat.

Stability: stable at room temperature and pressure, but easy to lose water of crystallization in heating or humid environment. When heated to a certain temperature, it will gradually lose the water of crystallization and transform into anhydrous yttrium sulfate.

Applications

Material Science: As one of the raw materials for the preparation of yttrium-based materials, Yttrium Sulfate Octahydrate can be used to synthesize yttrium compounds with special properties, which in turn can be used in the manufacture of high-performance ceramics, fluorescent materials and so on. For example, in the preparation of yttrium aluminum garnet (YAG) ceramics, yttrium sulfate can be used as a source of yttrium, and after a series of chemical reactions and processes, YAG ceramic materials with excellent optical properties are obtained, which are widely used in the fields of laser technology and lighting.

Chemical analysis: In analytical chemistry, Yttrium Sulfate Octahydrate can be used as a standard substance or reagent for quantitative analysis of certain elements. For example, by using the chemical reaction between yttrium sulfate and specific reagents, the content of other metal ions in the sample can be determined by analytical means such as titration or colorimetric method.

Catalyst field: Yttrium Sulfate Octahydrate can be used as a precursor or additive to catalysts for the catalytic process of some chemical reactions. Studies have shown that properly treated and modified yttrium sulfate can improve the activity and selectivity of some catalysts, and has potential application value in organic synthesis, environmental protection and other fields.

Agricultural field: rare earth element yttrium has a certain effect on the growth and development of plants, Yttrium Sulfate Octahydrate powder as a yttrium-containing compounds, can be used to a certain extent as a trace element fertilizer applied to agricultural production, the study found that an appropriate amount of yttrium elements can promote photosynthesis in plants, improve crop resistance, etc., but at present, relevant applications are still in the research and exploration stage. It has been found that yttrium can promote photosynthesis and improve crop resistance in appropriate amounts, but the relevant applications are still in the research and exploration stage.
