Gadolinium Sulfate, also called Gadolinium Sulphate is used for making optical glass and dopant for Gadolinium Yttrium Garnets. It has microwave applications and is used in fabrication of various optical components and as substrate material for magneto-optical films.
Besides, Gadolinium Sulfate is used in cryogenic work and in thermoelectric devices.
Colorless monoclinic crystals; density 3.01/cm3 (at 15°C); loses water of crystallization at 400°C; density of anhydrous salt 4.14 g/cm3; decomposes at 500°C; soluble in cold water; solubility decreases with rise in temperature.
Gd2(SO4)3?8H2O is used in cryogenic work; and in thermoelectric devices.
Gadolinium(III) sulfate is used as analytical reagents, in inorganic synthesis and electronic ceramics. It is also useful in cryogenic research.
The hydrated sulfate is obtained by dissolving gadolinium(III) oxide indilute sulfuric acid followed by crystallization:Gd2O3 + 3H2SO4 + 5H2O → Gd2(SO4)3?8H2O.
