Morphology Of The Native Oxide Film On The Surface Of Titanium Sponge-like And Spherical Powder Particles

It investigated by SEM morphology and thickness of the native oxide film on the surface of spherical titanium particles obtained by spraying the melt in an inert atmosphere as well as on the surface sponge titanium and titanium sponge particles obtained by thermal reduction of magnesium. It is shown that the greatest thickness has the oxide film on the surface sponge titanium and titanium sponge particles. Methods of X-ray micro spectroscopy estimated phase composition of the oxide film on the surface sponge and sponge particles. It is shown that it is composed predominantly of rutile (˞ 83,2%) and anatase (˞ 16,8%). The estimation of opportunities of titanium sponge and sponge titanium powders promising carriers of metal catalysts combined-cycle conversion of methane.
