Product Details

Lutetium oxide, Molecular formula: Lu2O3; Molecular weight: 397.9322. The pure product is a colorless powder with slight hygroscopicity, easy to absorb water and carbon dioxide from the air, and turns into basic lutetium carbonate. It is the weakest alkaline one in the yttrium group. Insoluble in water and cold acids, soluble in hot dilute acids.

Applications:

1. LuAG used in the production of LED phosphors

2. Used for special scintillation crystal growth additives such as LYSO.

3. Used for special scintillation ceramics.

4. Used for special glass additives.

5. Used for industrial electronic additives.

Lutetium Oxide

The production method of Lutetium oxide is mainly oxalic acid precipitation method, that is, Lutetium(III) chloride or Lutetium(III) nitrate solution is used as raw material, the Ph value is adjusted to 2 with oxalic acid, and lutetium oxalate is precipitated by adding ammonia water, which is heated, matured, separated, washed, dried at 110 ℃, and then burned at 900~1000 ℃ to form lutetium oxide.
