1791 by Rev w., Gregor (Britain, Cornwall) found that, in 1795, M.H. Klaproth (Germany, Berlin) also found the elements.
Usually in mineral titanium iron ore (ilmenite, FeTiO3) or rutile (rutile, TiO2) exist in nature, also with titanium magnetite, sphene and iron
High strength, acid and used in the manufacture of alloy, titanium dioxide for paints, rubber and paper pigment, also used as a lightweight materials manufacturing.
