Gadolinium Oxalate

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 of gadolinium(III) oxalate 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.
