General Materials Processing Notes

The authors cite J.A. Haglund et al., Journal of the American Ceramic Society, Vol. 56, No. 6, 327 (1973), and summarize the procedure as follows. "The Sm2O3 was produced from zeonotine ore by ion exhange, formation of the oxyacid salt, and calcination to yield the oxide."

Measurement Methods

Resonance method
The authors cite S. Spinner et al., American Society for Testing and Materials Proceedings, Vol. 61, 1221 (1961), and summarize the procedure as follows. "Elastic properties were measured by the sonic resonance technique. ... High-temperature measurements were made in a vacuum carbon-rod resistance furnace. ... Volume-fraction porosity is based on a theoretical density of 7.748 g/cm3..."
