بررسي فازي تركيبات MO+2 )1-X( SI+2XAI

The Phase Investigation of Mo + 2(1 - x)Si + 2xAI Compounds S.

X-ray powder diffraction data for M02.g5Al1.91Si4.g1 are presented here. The new Mo2.g5Ali 9iSi4.gi compound was successfully prepared, using the self-propagating high- temperature synthesis (SHS) technique. The starting atomic mixture of reactant powders was Mo + 2(1 - x)Si + 2xAl with 0.2 < x < 0.5. The final powder compound obtained by the SHS technique was determined to be in x — 0.2; Mo(Si, Al)2 and in 0.3 "S. x ^ 0.5; M02.g5Al1.9jSi4.8i. respectively X-ray powder diffraction pattern of M02.g5Al1.91Si4.g1 was recorded using an X- ray powder diffractometer and CuKa radiation that have been analyzed by automatic indexing programs. M02.g5Al1.91Si4.g1 was found to be hexagonal.
