摘要

The chemical system Ti-B-C-Cl-H was explored experimentally under reduced pressure (10 mbar) starting from a mixture of TiCl_4, BCl_3, CH_4 and H_2. The rate of growth, the composition, and the microstructure of the deposited solids were examined. The formation of titanium diboride, present in the entire explored domain, directs the chemical system. Carbon is present only in a small domain and when the concentration of TiCl_4 in the gas mix-ture is very low. Only rhombohedral boron carbide B_(13)C_2 and a tetragonal phase noted 'Q' with the general formula B_(48)Ti_(2-x)C_(2-y) were identified, and always in the presence of TiB_2. These solids are distinguished by their very unique and varied microstructures and with the notable existence of nanometric three phase composites.
