Abstract:

The first paper reports researches directed to assuring the required precision of determinations of impurities in Mo, which in this case were 0.0001 for tin, lead, bismuth and antimony, and 0.001 for zinc, copper, arsenic, chromium, titanium and nickel. The second paper describes quantitative determinations of tin, bismuth, lead, cadmium, antimony, copper, nickel, arsenic, zinc, chromium, titanium, magnesium, silicon, iron, aluminum in a relatively pure tungsten preparates. The metallic tungsten in the form of moldings and powder, the WO3 tungsten andydrite, the H2WO4 tungstic acid, and the NH42WO4 ammonium paratungstate are included among them.
