Synthesis of Gadolinium(III) Bromide and Modeling by the Experimental Design Method

In the present work, we have synthesizedgadolinium(III) bromide, GdBr3 from the gadolinium oxide, Gd2O3 by sintering brominating with ammonium bromide, NH4Br. The influence of three main synthesis parameters (contact time, stoichiometry, and temperature) on the reaction yield was studied and optimiz...
