It is difficult to obtain the pure metal, from the facility with which it becomes oxidized in the air. Symbol, Ba. Its oxide called baryta. [Rarely written barytum. Some of the compounds of this element are remarkable for their high specific gravity, as the sulphate, called heavy spar, and the like. The oxide was called barote, by Guyton de Morveau, which name was changed by Lavoisier to baryta, whence the name of the metal. Origin: NL, fr. Gr. Barys heavy.
