The Properties of Screen Printed (Bi,Pb)-Sr-Ca-Cu-O Thick Films Based On Decomposed Oxalate Powders
The significance of powder and paste characteristics was studied in order to improve the morphology and structure of superconducting (Bi,Pb)-Sr-Ca-Cu-O screen printed thick films. Powder with nominal composition of Bi1.75Pb0.4Sr1.9Ca2.1Cu3.2Oy was prepared via the oxalate route and decomposed at 430...

| description | The significance of powder and paste characteristics was studied in order to improve the morphology
and structure of superconducting (Bi,Pb)-Sr-Ca-Cu-O screen printed thick films. Powder with nominal
composition of Bi1.75Pb0.4Sr1.9Ca2.1Cu3.2Oy was prepared via the oxalate route and decomposed at 430 to
795℃. The decomposed powders were characterized by X-ray diffraction, transmission electron microscopy
and specific surface area measurements. These studies showed a variation of specific surface
area from 16.5 to 0.9 m2/g and a variation of the average particle size from 100 nm to 800 nm in the
studied temperature interval. The phase structure showed three distinct temperature areas; between
430 to 620, 620 to 715, and at 795℃. |
