general description barium alloy, pyrophoric is mixture of barium and other metals or nonmetallic elements to improve the specific usefulness of barium. barium alloys are a solid and can ignite spontaneously in contact with air. barium is toxic and products given off in fire could be very toxic.
air & water reactions finely divided metal powder is pyrophoric, ignites spontaneously in air [bretherick 1979 p. 170-171]. alloys containing a substantial proportion of barium rapidly decomposed water. the heat of the reaction is sufficient that the evolved hydrogen may ignite [lab. govt. chemist 1965].
reactivity profile alloys containing a substantial amount of barium react violently with acids [lab. gov. chemist 1965].
health hazard fire will produce irritating, corrosive and/or toxic gases. inhalation of decomposition products may cause severe injury or death. contact with substance may cause severe burns to skin and eyes. runoff from fire control may cause pollution.
fire hazard flammable/combustible material. may ignite on contact with moist air or moisture. may burn rapidly with flare-burning effect. some react vigorously or explosively on contact with water. some may decompose explosively when heated or involved in a fire. may re-ignite after fire is extinguished. runoff may create fire or explosion hazard. containers may explode when heated.
barium preparation products and raw materials
raw materials barium nitrate-->barium oxide
