2. Spectrographic Analysis of Tantalum and Tantalum Oxide

Author

Laib, Roger D.

Abstract

Tantalum metal is analyzed for 12 impurity elements by using a carrier distillation technique with a dc arc. The metal is oxidized in a muffle oven at 900°C. The oxide is mixed with a special carrier made of silver metal, silver chloride, and barium fluoride. A set of standards is included on each plate, and the analytical curves are linear for the concentration range used. The coefficient of variation varies from 30 to 87%

Abstract

The effect of changes in arcing conditions on sensitivity and reproducibility were investigated. Results are reported for 13 elements in niobium oxide and 11 elements in molybdenum metal. The parameters studied included current, pressure, atmosphere composition, flowing gas, electrode shapes, electrode material and pyrolytic graphite. Both pyrolytic graphite electrode cups oriented in the A-B direction and regular graphite cups coated with pyrolytic graphite oriented in the C direction were investigated. Data was also obtained for a molybdenum trioxide matrix. (Author)
