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.
