VANADIUM, in chemistry, a metallic pentad element, discovered by Sefstrom great London, in which he was his own archi- tect; but it did not prove a success.

It is extracted from the finely pulverized slag by defagrating with niter and sodic carbonate, jigesting the fused mass with a saturates solution of sal-ammoniac, and igniting rie prod- uct in an open vessel. On heating the mass with potassium, and washing with water, pure vanadium is obtained as a brilliant metallic powder, having a sil- ver-white luster. It is non-volatile, -does not tarnish in the air, burns vividly of Hanover, and the same year he was occupied with the erection of Blenheim Palace.

It forms five oxides, analogous to the oxides of nitrogen, and three chlorides, viz., the dichloride, the trichloride, and the tetrachloride. The addition of metallic vanadium in very small quanti- ties to chromium steel and other steels imparts to them a superior degree of tensile strength and elasticity.
