gallium usage and synthesis |
chemical properties |
light grey solid |
general description |
gallium is a silvery-white liquid at room temperature. ingestion of gallium may be toxic. gallium is corrosive to aluminum. if exposed to high temperatures, gallium may emit toxic fumes which may form a corrosive alkaline solution with water. gallium is soluble in most acids and alkalis. gallium is used as a semiconductor material. |
air & water reactions |
stable in dry air, in moist air gallium tarnishes |
reactivity profile |
metals, such as gallium metal, are reducing agents and tend to react with oxidizing agents (i.e. hydrogen peroxide). their reactivity is strongly influenced by their state of subdivision: in bulk they often resist chemical combination; in powdered form they may react more rapidly. reacts violently with chlorine and other halogens at ambient temperatures [bretherick, 5th ed., 1995]. |
health hazard |
inhalation of vapors or contact with substance will result in contamination and potential harmful effects. fire will produce irritating, corrosive and/or toxic gases. |
fire hazard |
non-combustible, substance itself does not burn but may react upon heating to produce corrosive and/or toxic fumes. runoff may pollute waterways. |
