Uranium boride

Uranium Boride, UB, is obtained in silverj -grey fragments by passing an electric arc between electrodes (made by compressing an intimate mixture of powdered metallic uranium and amorphous boron ) in a vacuum electric furnace. The boride is stable towards alkalies and acids, except hydrofluoric and nitric acids. It is readily attacked by fused alkali hydroxide. [Pg.337]
