Tantalum compounds (as Ta) Of low acute toxicity. Dusts mildly Irritating to the lungs. 5 mg/m (metal and oxide dusts, as Ta) 2500 mg/m (metal and oxide dusts, as Ta) Metal is a gray-black solid, platinum-white if polished. Odorless. Tantalum pentoxide is a colorless solid. Used in aerospace and other specialty alloys. [Pg.616]

Although very unreactive in massive forms, the finely divided metal may be pyrophoric, a Japanese study of this hazard has been reported [1]. Consequent upon an explosion in a tantalum dust collector, further study of powder explosion was made. Minimum ignition energies were found to be much lower than previously supposed. An oxide coating makes it susceptible to electrostatic charge generaton and discharge [2]. See entry PYROPHORIC METALS (references 3,9)... [Pg.1998]

EXPLOSION and FIRE CONCERNS metal is a combustible solid dry powder undergoes spontaneous ignition in air eontact of metallic dust with strong oxidizers may cause fires and explosion metal is incompatible with bromine trifluoride, fluorine, and lead chromate tantalum pentoxide is incompatible with bromine trifluoride, chlorine trifluoride, and lithium minimum explosion dust concentration is less than 200 g/cm (0.2 g/L) use dry sand, dry dolomite, and dry graphite for firefighting purposes. [Pg.924]
