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

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 Rot alloy with the matrix.
