Titanium is present in meteorites and in the sun.
Analyses of rocks obtained during earlier Apollo missions show lower percentages. Titanium oxide bands are prominent in the spectra M-type stars. The element is the ninth most abundant element in the crust of the earth. Titanium has a potential use in desalination plants for converting sea water into fresh water. The metal has excellent resistance to sea water and is used for propeller shafts, rigging, and other parts of ships exposed to salt water.
