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. Its tetrahydrate loses water by heating to obtain the anhydrous form, which then decomposes at high temperatures to generate gadolinium oxide and rhenium heptoxide.
