Abstract
Two cements have been found for propagating ultrasonic compressional and shear waves into small metal single crystals from a fused silica buffer rod at high temperatures in vacuum. A quasiwater glass cement composed of sodium silicate solution, sodium metasilicate powder, and calcium carbonate has been used for elastic constant measurements with zirconium and titanium single crystals up to 883°C. An epoxy phenolic resin has been used for a similar purpose with uranium up to 610°C for compressional waves and 350°C for shear waves. The optimum conditions for use of the cements are described. The elastic constant data are not included.
