Abstract

In fact, the largest percentage of worldwide use for titanium is
for the production of titanium dioxide rutile. It is used mainly as a white
pigment. The titanium dioxide pigment is manufactured by two ways
processing titanium-containing ilmenite minerals: the sulphuric process, the
most commonly used in Europe, and the process with chlorine, developed
about 1960. As it is necessary a sustainable technological development
regardless of the current amount of titanium ores, we proposed a novel
alternative way, the electrochemical oxidation of industrial titanium waste
to obtain titanium oxide anatase powder. Titanium specimens were
electrolytically oxidized at potential up to the breakdown potential in
simulated physiological solution at room temperature. The oxidation product,
a white powder, was characterized by X-Ray diffractometry, FTIR
spectroscopy and scanning electron microscopy with electron diffraction
spectroscopy. The results showed that this powder was a mixture of anatase
and brookite forms of TiO2.
