Gadolinium oxalate is existed in hydrate normally, which is monoclinic crystal. It is rare earth oxalate salt, which is hard to dissolve in water. The solubility in 25℃ water is just 0.55mg/L. Gd2(C2O4)3.10H2O is insoluble in water, but soluble in acids. It loses six water molecular at 110℃. Its production method is same as lanthanum oxalate. Gadolinium chloride or gadolinium nitrate is the raw material.

Gadolinium(III) oxalate hydrate get wide uses in extraction of rare earth elements specially extract rare earth metals elements from xenotime. It is also common raw material for rare earth oxides, especially production of PL phosphors and cathode ray fluorescent powder.
