I need help to find lattice constants, spacings and intencities from
powder diffraction files JCPDS of these substances :
    1. Complex M23C6 (PDF no. 5-0721)
    2. (Cr,Fe)7C3 (PDF no. 5-720)
    3. VC (1-1159 or 25-1002)
    4. TiC (6-614)
    5. NbC (10-181)
    6. HfC (9-638)
    7. ZrC (19-1487)
    8. Ni2W4C (20-796)
    9. (Cr,Fe)23C6
   10. (Fe,Cr)3C

Please help me. I need these data, primarily no.1 and 2, but I have a
problem with literature availability.
Thank you in advanced.

Sincerely,
Dryar U. Purba

Often, a PDF can be found at a local university (local being a
relative term here :-).  If you have not found a source, I will be
glad to help, but I would need to be certain you have no other access
to this information first.  It would take quite a bit of trouble to
obtain and transmit these pattern data.

Cheers,
Bryan
