The invention relates to a method for removing vanadium impurity from titanic tetrachloride. The invention prepares titanium trichloride serum by the reaction between the cost aluminum powders with the average grain size no bigger than 150mum after surface activation treatment. TiCl3 in the serum reduces VOCl3 in the titanic tetrachloride to be VOCl2 deposit so as to remove the vanadium.
For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/m³). As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/ft³ (pounds per cubic foot) and if we know that a sample of aluminum has a sg of 2.5 then we can calculate that its density is 2.5 x 62.4 = 156 lbs/ft³.
