Main Text
Columbium, which melts at a torrid 4,380∞ Fahrenheit, finds uses in turbo-jet and rocket engines where it improves heat resisting qualities and impact strength of other metals. Dr. E. H. Nickel, of Federal Department of Mines and Technical Surveys, examines rock sections of columbium ore with petrographic microscope.
