"Elastic Properties of Polycrystalline Yttrium Oxide, Holmium Oxide, and Erbium Oxide: High-Temperature Measurements," W.R. Manning and O. Hunter, Jr., Journal of the American Ceramic Society, Vol. 52 [9], pp. 492-496 (1969), published by American Ceramic Society.

General Materials Processing Notes

The authors cite W.R. Manning et al., J. Am. Ceram. Soc., Vol. 52, No. 8, 436 (1969), and summarize the procedure as follows. "The specimens of Y₂O₃, Ho₂O₃, and Er₂O₃ were chosen from those used in the room-temperature investigation. The fabrication process involved cold-pressing the powdered oxide into a rectangular prism, sintering the sample, and finally grinding to exact dimensions."

Measurement Methods

Resonance method

The authors cite M.O. Marlowe et al., J. Am. Ceram. Soc., Vol. 48, No. 5, 227 (1965), and summarize the procedure as follows. "The temperature dependence of the elastic moduli was determined by the dynamic resonance method... The fundamental flexural and torsional resonant frequencies were measured as functions of temperature... The high-temperature data were obtained under vacuum at pressures less than (6.7 mPa = 0.05 µm Hg). The specimen was suspended by Hitco-C carbon yarn in a carbon-rod resistance furnace. Temperature was measured with a Pt-Pt10Rh thermocouple with its hot junction located near the middle of the sample."
