A Plasma-Arc Technique for the Spectrochemical Determination of Titanium and Zirconium in Molybdenum
A plasma-arc technique has been developed for the spectrochemical determination of titanium and zirconium in molybdenum alloys. Titanium is determined in the 0.25–1.5% range and zirconium in the 0.05–0.4% range with an overall precision of about ±5% and an accuracy which approaches the precision. Sensitivity for the zirconium determination is achieved by using high gas flow and high amperage. Molybdenum is used as the internal standard and a background correction is necessary to produce a straight-line analytical curve for zirconium over the concentration range of interest.
