Ruthenium sulfide Powder is used to prepare sintered material, which is a semiconductor. It acts as an electrode and possesses high catalytic activity for oxygen evolution from aqueous solution.
Laurite is an opaque black, metallic ruthenium sulfide mineral with formula: RuS2. It crystallizes in the isometric system. It is in the pyrite structural group. Though rare, it occurs in many parts of the world.
Laurite has a Mohs hardness of 7.5 and a specific gravity of 6.43. It can contain osmium, rhodium, iridium, and iron substituting for the ruthenium.
It occurs in ultramafic magmatic cumulate deposits and sedimentary placer deposits derived from them. It occurs associated with cooperite, braggite, sperrylite, other minerals of the platinum group elements and chromite.
Synthetic RuS2 is a highly active catalyst for hydrodesulfurization
