Beschreibung
Zusammenfassung:	The invention relates to a method for stabilising liquid mercury using sulfur polymer cement, via mercury sulfide. Said method for stabilising liquid mercury by the production of sulfur polymer cement comprises (a) transformation of the liquid mercury into mercury sulfide (metacinnabar) by a chemical reaction, under stoichiometric conditions, between mercury and elemental sulfur; and (b) production of sulfur polymer cement by incorporating the mercury sulfide produced in the previous step into a stable mixture consisting of aggregates, elemental sulfur and a sulfur polymer.
