ABSTRACT:
A dispersion of up to about 70 weight percent elemental sulfur in an aqueous ammonia solution of at least one metal compound selected from the group consisting of soluble zinc and magnesium compounds has reduced corrosive activity toward ferrous metal. The atomic ratio of zinc and/or magnesium to sulfur is from about 0.0002 to about 0.1 and the mole ratio of ammonia to metal compound is from about 0.1 to about 200.
