We have perfected processes for the synthesis of lanthanum, gadolinium, and yttrium oxyselenides by heating oxides in flowing hydrogen and selenium vapor. The optimal selenidation temperature is 700°C for lanthanum, 850°C for gadolinium, and 900°C for yttrium. Subsequent annealing of the materials in flowing hydrogen at 1000°C makes it possible to remove trace levels of amorphous selenium and impurity phases containing diselenide groups.
