OSMIUM (IV) OXIDE Usage And Synthesis

Chemical Properties

dark bluish black powder(s), with rutile crystal(s) form [KIR82] [ALD94]

Uses

The osmium oxide/hexacyanoruthenate films modified electrodes plays an important role for the electrocatalytic reaction of catecholamines and sulfur oxoanions. Used as catalyst. Metallic osmium or an osmium oxide-ruthenium cyanide film modified graphite electrodes plays an essential role for the determination of biogenic amines from electrocatalytic responses.

Safety Profile

Brown or black crystals. Amorphous form can explode spontaneously in air. When heated to decomposition it emits toxic fumes of Os.
