ስለ Vanadium
Vanadium is a hard, silvery-gray, ductile transition metal rarely found free in nature. About 80% of vanadium is used in ferrovanadium steel alloys. It was discovered twice -- first in 1801 by del Rio, then rediscovered in 1831.
ፕሮግራሞች
Steel alloys, vanadium redox batteries, titanium-aluminum-vanadium aerospace alloys, and catalysts.
ሐቅ
Vanadium was discovered, then lost, then rediscovered -- del Rio found it in 1801 but was talked out of his discovery.
