Mechanical properties of Bi2Sr2Ca2Cu3O10

Abstract

Bi2Sr2Ca2Cu3O10 (Bi-2223) ceramics was synthesized by melt-quenched method at 1200 oC for
30 min and their physical properties were measured. Microstructures of the ceramics were observed by using
the scanning electron microscope (SEM). The crystal structures were measured and simulated by using x-ray
diffraction (XRD) technique and visualization of crystal structure (VICS) software, respectively. Elastically
properties and micro-hardness were measured and evaluated by using ultrasonic sound velocity measuring
device and micro hardness tester, respectively. It found that, the Bi2Sr2Ca2Cu3O10 ceramics is the amorphous
behaviour confirmed by the XRD analysis. The Bi-2223 ceramics has been a good value of bulk modulus
(K), Young’s modulus (E), Shear modulus (G) and Vickers hardness (Hv), these properties was
corresponded to the base thermoelectric materials.
