DETERMINATION OF COMBINED NITROGEN IN TITANIUM METALS

Technical Report · Thu May 10 04:00:00 EDT 1956

OSTI ID:4263489

The metal is dissolved in hot 6 N sulfuric acid and hydrogen peroxide. Ammonia separated by distillation from alkaline solution is determined absorptiometrically using either sodium phenate/sodium hypochlorite for samples containing 5 to 90 ppm combined nitrogen or Nessler's reagent for samples containing 90 ppm to 1.0% combined nitrogen The method has been used for pure powder, sponge, or wrought titanium metal containing 5 ppm to 1.0% combined nitrogen At the 10 and 90 ppm levels results show a negative bias of about 5% with a coefficient of variation of plus or minus 4%. At the 500 ppm and 0.75% levels results are quantitative with a coefficient of variation of about plus or minus 3%. (auth)
