For the manufacture of light-alloying vanadium alloys and first of all, pure vanadium is required to protect and equal to the available vanadium oxide, while for the use of iron, vanadium is used. This is the reason for the search for new alloying vanadium-containing materials. Due to this, it was recommended to use vanadium slag, which is obtained by oxidizing 20 vanadium cast iron, as a result of the reduction of vanadium material.

The proposed material for alloying vanadium metal possesses the following advantages compared with the known:

- a higher rate of growth

- Ensures a decrease in the profitability of the alloying of the metal with vanadium; - increases the extraction of vanadium in the metal and reduces the cost of alloying the last vanadium.

The basic and very important accessibility of the material offered is that it is very fast in liquid metal, such as cast iron or steel.
