ABSTRACT:
A method is disclosed for the preparation of metal reference samples for spectrographic analysis. The method consists of producing a substantially cylindrical preform or blank by spray deposition, followed by the consolidation of the blank in the form of a bar having an appropriate diameter and finally the cutting of the reference samples therefrom. Compared with the prior art methods, the method offers the advantages of an improved chemical homogeneity and low oxygen content.
