Product performance
We have the chemical La(OH) 3. Molecular weight 189.93. White powder. Insoluble in water, soluble in acids. Has a strong alkaline, can swap out from the ammonium salt and ammonia absorption of CO2 in the air, thermal decomposition, 260 ℃ water loss, water loss generated after La2O3 · H2O. At high temperature, it completely loses water and becomes La2O3.

Applications
Catalyst, glass, ceramics, electronic industry etc.

Storage condition
Store in a sealed container and place in a cool, dry place.
