Hi all,
This is an interesting discussion of quantitative phase analysis. It sounds to
me from what Pam is saying that we can calculate an esd for each phase if we
know its particle size, and that the rela

Hi Pam,
maybe a misunderstanding: I did not try to discuss the amount of
"amorphous" material in cements. I'm aware of the problem, but a
careful Rietveld analysis with an internal standard should be able to
matched the weighing figures quite nicely.

Hi Lubo,
the difference between 6 and 7 % MgO is bigger than 15 % relative
a reduced setting time - any guesses as to why this might be? :-)

Hi Lubo,
the difference between 6 and 7 % MgO is bigger than 15 % relatively,
thus the error by wrong re-scaling (e.g. if 10 % "amorphous" are
missing) is smaller than the error discussed. And, if the "true" content
of periclase should be about 5 %, than a measured value of 7 % is worth
to be
Hi,
I really wonder why do you bother about 1% difference when the error of
the method (XRD, quantitative phase analysis) could reach 10%
(absolute) ...
People in the discussions appearing here seem to forget about two things:
i) "quantitative" phase analysis done by rietveld method is always
11 matches
