Publisher's Synopsis
Excerpt from Rapid Methods for the Chemical Analysis of Special Steels, Steel-Making, Alloys, and Graphite
IN offering this little volume the author desires to call attention to the portions of it that he has worked out in his own way and that are, as far as he is aware, new features. (1) A qualitative test for titanium in the presence of vanadium. (2) The annealed test for ebro mium in steel. (3) The test for annealing in steel. (4) The pouring Of the indicator into the solution when titrating for vanadium and chromium in steel, in the presence of either or both elements. (5) The determina tion of small amounts of copper and nickel in steel and ferro-vanadium by first separating the copper and nickel from the bulk of the iron and vanadium by means of potassium ferricyanide. (6) The exact determination of phosphorus in ferro-vanadium, demonstrating that as little as one-eighth of the actual phosphorus may be Obtained by the ordinary processes. (7) The application of the new heating wire to a combustion tube. (8) The modified method for higher per cents of nickel. (9) The determination of Silicon carbide in old plumbago crucibles and its existence therein. (10) The automatic labora tory still. (11) The simple laboratory method for making clay combustion boats. (12) The method for annealing Hadfield's steel. (13) The author's method for the rapid volumetric determination Of manganese in the presence of iron, Calcium and magnesium, by means of potassium ferricyanide. (14) The new form of potash absorption and weighing apparatus for carbon dioxide. (15) The new form of combustion train.
