Popis: Original techniques have been developed enabling both shear and longitudinal ultrasonic waves to be dry-coupled into green and sinteredstate ceramics via elastomers using minimal pressure. These techniques permitted the velocity measurements to be made at megahertz frequencies, from which the elastic moduli were calculated using independent density measurements. Velocity differences between samples composed of hard agglomerates and samples composed of soft agglomerates were observed for green and intermediate sintered states, but not for the (near) dense states.
