Bi2Sr2Cax-1CuxO6+ (BSCCO, x=1, 2, and 3) glassy plates have been synthesized by melt-quenched method and the mechanical properties are measured. The microstructures of BSCCO glassy plates are observed by the scanning electron microscope (SEM). The crystal structures of the glasses are measured and simulated by x-ray diffraction (XRD) technique and visualization of crystal structure (VICS) technique, respectively. The elastically properties and Vickers hardness are measured and evaluated by ultrasonic sound velocity measuring device and micro-hardness tester, respectively. It found that, the BSCCO glassy plates are composed ofBi2Sr2CuO6 (Bi-2201), Bi2Sr2CaCu2O8 (Bi-2212) and Bi2Sr2Ca2Cu3O10 (Bi-2223) phases, these phases confirmed by the XRD analysis and calculated by Powder Cell technique. The glassy plates have been a good value of bulk modulus (K), Young’s modulus (E), shearmodulus (G) and Vickers hardness (Hv), these properties are corresponded to a good thermoelectric materials.
