Abstract:

The preparation of small amounts of alloys for use as spectrographic standards by melting the constituents in an arc button melting furnace is a common practice. Larger amounts for use in round robins or as long term chemical standards are prepared by normal foundary techniques. In both cases the levels of trace or contaminant elements obtained are difficult to predict, particularly when they are volatile at the melt temperature or do not alloy with the matrix.
