Rare Earth Sulfates

The general formula of rare earth sulfate is RE2(SO4)3nH2O, where that can be 0, 3, 4, 5, 6, 8, 9. Rare earth sulfate is sulfuric acid and rare earth oxide, hydroxide or carbonic acid Synthesized by the action of salt. Anhydrous rare earth sulfates are hygroscopic powders that dissolve well in water and release heat. The solubility of sulfate powder decreases with increasing temperature. For different types of rare earth sulfates, their solubility varies greatly.

Alfa Chemistry has an experienced team that has been engaged in the research of rare earth compounds for many years and provides customers with high quality rare earth compounds. The related products we can provide include:

Synthesis method and performance

  • The synthesis method of rare earth sulfate is as follows:
    3H2SO4 + RE2O3 = RE2(SO4)3 + 3H2O
    3H2SO4 + RE2(OH)3 = RE2(SO4)3 + 3H2O
    3H2SO4 + RE2O3 = RE2(SO4)3 + 3H2O
  • Stability: When the rare earth sulfate is heated, RE2(SO4)3 will be obtained at 155-260 ℃. When heated to 850-950 ℃, SO3 will be lost to form RE2O2SO4. When the temperature rises to 1050-1150 ℃, RE2O3 will be formed.
  • Performance: Rare earth sulfates and sulfates of monovalent cations such as alkali metal ions can form rare earth sulfate double salts, which can be represented by xRE2(SO4)3·yM2SO4·H2O, n=0, 2, 8, M is Na+, K+, Rb+ and NH4+ etc. As the atomic number increases, the solubility of rare earth sulfate double salts will increase, and the solubility of light rare earth sulfate double salts is relatively small.

Research on synthetic methods

Our researchers focus on the development and exploration of high-performance rare earth compounds, and support the exploration of multiple synthesis methods, making the synthesis of rare earth compounds with mild conditions, easy operation and controllable products. Most rare earth compounds have luminescent properties, and the control of the synthesis method makes the performance of the synthesized compounds controllable, so that they can be used in a wider range of applications.

Product customization

Alfa Chemistry's researchers have many years of experience in the research field of high-quality rare earth compounds, with many years of customization experience, and are capable of providing high-quality products to customers around the world. We also have a professional quality control platform, which can strictly control the quality of materials and meet industry norms and standards.
