OSMIUM (IV) OXIDE Chemische Eigenschaften,Einsatz,Produktion Methoden

• Chemische Eigenschaften

  Osmium (IV) oxide is a dark bluish black powder(s), with rutile crystal(s) form [KIR82] [ALD94]. Insoluble in water and acids. Forms OsO4 on heating in air; readily reduced to the metal by H2.

• Verwenden

  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.

• synthetische

  Osmium (VIII) oxide is reduced in the cold by a stream of H2. If, however, the OsO4 is heated in the H2 stream, the product is the metal. Osmium (IV) oxide can also be prepared by heating a fine powder consisting of a mixture of K2OsCl3 and three times its amount of Na2C03. The temperature should be lower than red heat; the cooled product is extracted with water which is slightly acidified with dilute hydrochloric acid. The product is perfectly pure OsO2.

• Sicherheitsprofil

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

• Structure and conformation

  Crystal structure of Osmium (IV) oxide: rutile type.
