process for the production of reference samples for spektralanalytische investigation.

摘要

Method of preparation of metal reference samples for spectrographic analysis. …??The method consists in producing a substantially cylindrical preform by spraying/deposition, in then consolidating this blank in the form of a bar of appropriate diameter and, finally, in cutting the reference samples from it. …??This method, when compared with those of the prior art, offers the advantages of an improved chemical homogeneity and of low oxygen contents.
