Preparation
Beryllium sulfide powders can be prepared by the reaction of sulfur and beryllium in a hydrogen atmosphere by heating the mixture for 10-20 minutes at temperatures from 1000-1300 °C.
Alternatively, it can be prepared by the reaction of beryllium chloride and hydrogen sulfide at 1150 °C, though this reaction will leave chlorine impurities.
