Determination of nitrogen in an aluminium-killed steel by an isotope-dilution method using Al(15)N.
Nitrogen in an aluminium-killed steel was determined by an isotope-dilution method using synthesized aluminium nitride enriched with (15)N. The results were in agreement with those obtained by chemical determination, whereas the vacuum fusion method with iron and platinum baths, and the isotope-dilution method using gaseous (15)N-enriched nitrogen, did not give accurate results.
