Discussion on “metallic tungsten and some of its applications” (Coolidge), and “the convection and conduction of heat in gases” (Langmuir), Boston, Mass., June 25, 1912. (see proceedings for June, 1912)

C. M. Green: Dr. Wientraub of the research laboratory at Lynn has suggested a new use of tungsten, that is as a substitute for platinum leading in wire for rectifier tubes. I am thoroughly satisfied from experiments I have made that it will be better than platinum. The specific resistance is about one-half that of platinum, or about 5 to 6 microhms per cu. cm., while the platinum which we use at the present time is about 13 to 14 and the platinum used a few years ago had a specific resistance of 30 to 40 microhms.
