Abstract
Titanium oxides such as rutile and anatase, are materials that stand out for exhibiting properties that act in biomedical and photocatalytic applications, among others. It is extreme importance to idealize new techniques that produce such compounds, being indispensable the improvement of characterizations for these materials. For this purpose, titanium comercially pure (CP) grade II cylindrical samples were oxidized ionically using titanium cage electric shields, oxidized at 350 ° C in 3 and 8 hours. Through Grazing Incidence X-ray Diffraction (GIXRD) analysis, was observed on the surface of the treated samples the formation of a TiO2 film with the anatase, rutile and brookite phases, the latter phase cited being difficult to produce in conventional thermochemical treatments. All samples treated showed a significant increase in wettability using distilled water. The higer value was for the sample with a 8 hours treatment time, in which this condition presented phases with greater intensity in the analysis of GIXRD
Highlights
Titanium compounds are being extensively studied due to the large number of industrial applications, when elements such as hydrogen, carbon, nitrogen or oxygen are added in their crystalline lattice
The great affinity of titanium with these elements occurs because this metal has an incomplete electronic configuration, in other words, it has free "d" orbitals that promote the formation of chemical bonds with interstitial elements (H, C, N and O)[1,2]
The Grazing Incidence X-ray Diffraction (GIXRD) technique is important because of the small depth of beam penetration in the deposited layer, providing information about the diffusion profile that occurred in the treatment
Summary
Titanium compounds are being extensively studied due to the large number of industrial applications, when elements such as hydrogen, carbon, nitrogen or oxygen are added in their crystalline lattice. Titanium is found in the form of oxide, the best known as TiO2 It is widely used because it is chemically inert and has characteristics such as biocompatibility, good dielectric properties, excellent absorption in the ultraviolet spectrum, high stability and is applied in different industrial areas such as solar cells, environmental purifiers, biomaterials, protective layers against corrosion, nanomaterials[3,4,5,6]. Among the existing titanium oxides compounds, titanium dioxide, TiO2, draws attention to possess important properties scientifically and industrially, and can be found in different crystalline structures, the best known being brookite, anatase and rutile. The anatase and rutile crystallizes in the tetragonal structure and brookite crystallizes in orthorhombic[7,8,9,10]
