The production of carbon nanostructures, including carbon nanotubes (CNTs), by chemical vapour deposition (CVD) occurs by thermally
induced decomposition of carbon-containing precursors. The decomposition of the feedstock ...

Titanium nitride in upgraded nitrided ilmenite (bulk of iron
removed) can selectively be chlorinated to produce titanium
tetrachloride. Except for iron, most other components present
during this low temperature (ca. ...

Industrial production of titanium occurs via the batch-wise reduction
of titanium tetrachloride (TiCl4) with a reducing metal, being
magnesium in the Kroll process, or sodium in the Hunter process. In
the search for low ...
