Using the SHS method, the titanium, vanadium and chromium based multicomponent carbohydrides of variable compositions were synthesized. The synthesis of complex carbohydrides with Ti and Cr was conducted in one technological stage: xTi + (1 - x)Cr + yC mixture (0.4 <= x <= 0.8 and 0.4 <= y <= 0.6), was pressed to the tablet and ignited in the argon or hydrogen environment (P = 2 atm). At syntheses of complex carbohydrides including titanium, vanadium, and chromium, the metal/carbon compositions xTi + (1 - x) (V + Cr) + yC (0.6 <= x <= 0.9 and 0.35 <= y <= 0.6), were studied. The X-ray analysis demonstrated that in SHS mode, only carbohydrides with FCC lattice formed. It was demonstrated that at high content of titanium and carbon, monophase products formed. It was shown that at the vanadium insertion into the system, single-phase carbohydrides with FCC structure can be received possessing very low dissociation temperature. The temperatures of DTA decomposition were defined: within 360-530 degrees C in Ti-Cr-C-H system, but within 340-400 degrees C Ti-Cr-V-C-H system. The hydrogen liberation occurred with one endoeffect. (C) 2010 Professor T. Nejat Veziroglu. Published by Elsevier Ltd. All rights reserved.
