The chemistry of boron and titanium diboride formation: Decomposition of TiCl{sub 4} and BCl{sub 3} in hydrogen and helium
Measurements of the decomposition of mixtures of boron trichloride (BCl{sub 3}), titanium tetrachloride (TiCl{sub 4}), and hydrogen at elevated temperatures are presented. The decomposition of BCl{sub 3} with hydrogen appears to drive the chemistry in this system. The species depositing boron on the surface contains at least 2 chlorine atoms. Once deposited, the surface chlorine is removed by reaction with hydrogen to form HCl and, presumably, surface B-H bonds.
