Beryllium sulfide (BeS) is an ionic compound from the sulfide group with the formula BeS. It is a white solid with a sphalerite structure that is decomposed by water and acids.[3]
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. If done at 900 °C, there is beryllium metal impurities.[4]
Alternatively, it can be prepared by the reaction of beryllium chloride and hydrogen sulfide at 900 °C.[3][4]
