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]

Indium(III) sulfate (In2(SO4)3) is a sulfate salt of the metal indium. It is a sesquisulfate, meaning that the sulfate group occurs 11/2 times as much as the metal. It may be formed by the reaction of indium, its oxide, or its carbonate with sulfuric acid. An excess of strong acid is required, otherwise insoluble basic salts are formed. As a solid indium sulfate can be anhydrous, or take the form of a pentahydrate with five water molecules or a nonahydrate with nine molecules of water. Indium sulfate is used in the production of indium or indium containing substances. Indium sulfate also can be found in basic salts, acidic salts or double salts including indium alum.
