Behavior of vanadium during reduction and smelting of vanadium
Vanadium titano-magnetite is an important iron ore resource containing iron, vanadium and titanium. Although iron and vanadium can be recovered by the traditional blast furnace process, titanium can only be stored in the form of TiO2 bearing slag, which resulting in a great waste of titanium resources.

Vanadium
Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium alloys are used in nuclear reactors because of vanadium's low neutron-absorbing properties.

Thermophysical properties of titanium and vanadium nitrides
To achieve this, we have considered titanium and vanadium nitrates (TiN and VN) instead of pure metals as has been done by Glensk et al. [7]. These two materials are of importance in many materials science applications because of their good mechanical, chemical and thermal properties. The rest of this paper is organized as follows: first the ...
