Information circular 7953 Washington U.S. Dept. of the Interior, Bureau of Mines, 1960, 46 p.THIS BIBLIOGRAPHY has been assembled to aid research by the Bureau of Mines and others on high-purity tungsten. It appears approximately 50 years after the development of ductile tungsten-one of the first metals to be produced in a high-purity form. Requirements of the missile age are ever more demanding that engines run hotter and space vehicles fly higher and faster. Thus, it has become necessary to reexamine all conventional materials of construction as well as to investi' te new combinations. At this stage of our technology we have alloys capable of operation at 1,8000 F. and several possibilities of developing some that will be satisfactory up to 2,5000 F. Strength-weight comparisons, detrimental to tungsten at lower temperatures, disappear at this point, and tungsten or its alloys appear to be the only metal capable of operation at truly high temperatures. The aim of this bibliography has been to include only references that concern improving the purity of tungsten-from processing the ore to treating the finished metal. In this sense it is a selected and not a critical bibliography. The period from January 1911 through February 1959 has been covered. Because recent literature has the greatest value, most of the selected items refer
to publications issued within the past 5 years.
