Spectrochemical analysis of slag with a direct reading spectrometer (Direct Reader by Baird Atomic Inc., J.S.A. was used) is adequately accurate by the use of the briquetting method of analyzing by spark discharge the briquette made of the sample and graphite powder.But the working curve for slag is of no avail for other oxide materials of very different composition such as bricks, clay, cement, iron ore and iron sand, for the intensity of central line of grating spectrum used as the internal standard varies with the kind and concentration of base component of the sample. In analyzing powdered oxide materials in general, the kind and concentration of the base component can be made equalized to all the samples by the addition of some pure oxide compound. By comparison tests of various pure oxides, the addition of molybdenum trioxide is found to give working curves for the briquetting method of analysis common to several oxide materials.
