Gadolinium perrhenate is an inorganic compound, with the chemical formula of Gd(ReO4)3. It can be obtained by dissolving an excess of gadolinium oxide in a perrhenic acid solution (240 g/L) in the presence of hydrogen peroxide, from which the hydrates are precipitated.[2] Its tetrahydrate loses water by heating to obtain the anhydrous form,[3] which then decomposes at high temperatures to generate gadolinium oxide and rhenium heptoxide.[2]
