Does anyone have references for structures relating to
Sodium Oxalate (Na2 C2 O4)?
(There seems to be nothing in the ICDD database but you
would normally think someone has done this in the past(?))
Also, are there any papers exploring the phase equilibria of
Na2 C2 O4 - perferably giving crys

You
should multiply all of the crystalline phases by 5/7 with the remaining 2/7
being your amorphous phases.

Dear all
I'm doing quantitative analysis on a mixture
of 6 or 7 phases and I must to know the weight fraction of amorphous
phases.
I'm using Si as internal standard but I'didn't
understand if I must consider the relative or absolute difference between the
real and calculeted quantity.

Thanks Petr and Patrick for this odd solution: it works!

Hello Arie,
You have to set the same parameter number for gama and a.
for instance for Al2O3:
! a b calpha beta gamma
4.771113 4.771113 13.027040 90.00 90.00 120.00
81.0 81.0 91.00.00.0 81.0

Hi all,
I have a problem concerning the refinement of the cell parameters of a
rhombohedral space group (R-3c) in Fullprof. The documentation says to use
the hexagonal description of the unit cell and that is what I do: a=b, c,
alpha=90, beta=90, gamma=120. a and b are the refinable parameters, t
