barium oxide usage and synthesis
chemical properties white to cream powder
general description a white to yellow powder. may be toxic by ingestion. irritates skin, eyes and mucous membranes. used as a drying agent for gasoline and solvents.
air & water reactions hygroscopic. reacts readily and exothermically with water to form a solution of corrosive barium hydroxide [merck 11th ed. 1989].
reactivity profile barium oxide reacts as a strong base. combines exothermically with all categories of acids. reacts with carbon dioxide to form barium carbonate [merck 11th ed. 1989]. ignites hydroxylamine on contact [mellor 8:291 1946-47]. mixtures with mercurous or nickel oxide react vigorously with hydrogen sulfide in air. explosions may result [mellor 10:140 1946-47]. can react, particularly in the presence of moisture, with aluminum and zinc)to form oxides or hydroxides of the metal and generate gaseous hydrogen. may initiate polymerization reactions in polymerizable organic compounds, especially epoxides. may generate flammable and/or toxic gases with ammonium salts, nitrides, halogenated organics, peroxides, and hydroperoxides.
health hazard toxic; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. reaction with water or moist air will release toxic, corrosive or flammable gases. reaction with water may generate much heat that will increase the concentration of fumes in the air. fire will produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. contact with metals may evolve flammable hydrogen gas. containers may explode when heated or if contaminated with water.
