The Ru sulfides obtained by the element synthesis and 2 wet methods were studied by using static and dynamic coulometric titration The composition and formula of Ru sulfides were determine, and the kinetics of the reduction of the compounds by H2 at high temperature were studied. Possibly the original noncryst. compound of Ru2S3.10H2O possessed the structure of RuS.RuS2.10H2O.
