What powder did you try to sinter in an alumina crucible?
Michael Dahms
You must check by separate experiments, which acids dissolve the above mentioned compounds.
Very often, a crucible can be just used once, if strong reactions with the sintered powder occur. Or a certain crucible is always used for a certain type of powder.
