Ferroniobium is produced through electric-furnace aluminothermy using pyrochlore concentrate or technical niobium pentoxide. It is used in the smelting of structural steel and heatresistant alloys.
A silvery, soft, ductile metallic element that occurs chiefly in columbite-tantalite and is used in steel alloys, arc welding, and superconductivity research.
A mineral from which iron can be extracted that contrains metal that is valuable enough to be mined.
A very hard, heavy, gray metallic element that is exceptionally resistant to chemical attack below 150°C. It is used to make light-bulb filaments, electrolytic capacitors, lightning arresters, nuclear reactor parts, and some surgical instruments.
A bright white, soft, ductile metallic element found in several minerals, notably vanadinite and carnotite, having good structural strength and used in rust-resistant high-speed tools, as a carbon stabilizer in some steels, as a titanium-steel bonding agent, and as a catalyst.
Oka (Cayuga: Ganehsada:geh ) is a Canadian village on the northern bank of the Ottawa River (Rivière des Outaouais in French), northwest of Montreal, Quebec.
