Synthesis of BSCCO Amorphous Materials by Melt-Quenched Method

Abstract

Bi₂Sr₂Ca_x-1Cu_xO_6+d(BSCCO, x = 1, 2, and 3) amorphous materials have been synthesized by
melt-quenched method and the mechanical properties can be measured. The microstructures of amorphous
materials can be observed by the scanning electron microscope (SEM). The crystal structures of the glasses
can be measured and simulated by x-ray diffraction (XRD) technique and visualization of crystal structure
(VICS) software, 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
amorphous materials are composed of Bi₂Sr₂CuO₆(Bi-2201), Bi₂Sr₂CaCu₂O₈(Bi-2212) and Bi₂Sr₂Ca₂Cu₃O₁₀
(Bi-2223) phases, these phases confirmed by the XRD analysis and calculated by Powder Cell software. The
amorphous materials have been a good elastic value of bulk modulus(K) Young’s modulus(E), shear modulus(G) and Vickers hardness(H_V), these properties are corresponded to a good thermoelectric materials.
