Effect of Cu2+ ions on thermal stability and phase separation in Bi2Sr2CaCu2Ox glass

Possible observation of a glassy ferroelectric:Bi1.8Pb0.3Sr2Bahgat1, Kamel2 2000Phys. Rev. B1211161View full textAdd to dashboardCite

“…A similar result was observed on comparable glass. 16 The glassy state of the as-quenched sample was monitored also by DTA. The sample was heated from room temperature up to 900°C with a rate of 20°C/min.…”

Critical aspects on preparation of Bi-2223 glassy precursor by melt-process

“…10. The as-quenched material of Bi 2 Sr 2 CaCu 2 O 8 and Bi 4 Sr 3 Ca 3 Cu 4 O 16 were found to be completely amorphous as also presented in the literature [4,12,66].…”

“…1) as well as crucible material and conditions was found [8,[10][11][12]14,15,[17][18][19][20][21][23][24][25][26]28,30,. The melt temperature and time should be chosen as low as possible to avoid the evaporation of Bi and Pb but ensuring a complete melt.…”
