Calcium silicide

Calcium silicide Chemische Eigenschaften,Einsatz,Produktion Methoden

• Allgemeine Beschreibung

  An off-white solid. Density 2.5 g / cm3.

• Air & Water Reaktionen

  Decomposes on contact with water or moisture in air to form flammable gaseous hydrogen [AAR 1991]. Insoluble in cold water; decomposes in hot water [Hawley].

• Reaktivität anzeigen

  Calcium silicide reacts with acids to form gaseous silicon hydride, which ignites spontaneously in air [Lab. Gov. Chemist 1965]. Burns readily in fluorine [Mellor 6:663 1946-47].

• Health Hazard

  Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.

• Brandgefahr

  Produce flammable gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Runoff may create fire or explosion hazard.
