Heat Resistant Porcelains
DOI: 10.1063/1.3066275
The National Bureau of Standards has found that several of its previously developed porcelains behave in a more satisfactory manner in tests of bending at high temperatures and of resistance to thermal shock than do the best available high‐temperature metal alloys. In response to a request made in 1944 by the National Advisory Committee for Aeronautics, the Bureau has conducted a study of materials for use under conditions involving temperatures of eighteen hundred degrees Fahrenheit and above. An experimental gas turbine, using blades fabricated from the ceramic body of the most promising strength and creep characteristics, has been operated successfully in the Cleveland Laboratory of the National Advisory Committee for Aeronautics.
