Some lunar rocks contain high concentrations of the dioxide, TiO 2 . Titanium oxide bands are prominent in the spectra of M-type stars. Isolation Here is a brief summary of the isolation of titanium. Titanium is readily available from commercial sources so preparation in the laboratory is not normally required. In industry, reduction of ores with carbon is not a useful option as intractable carbides are produced.
Air is excluded so as to prevent contamination of the product with oxygen or nitrogen.
This can be melted under a helium or argon atmosphere to allow casting as bars.
