The oxygen nonstoichiometry of BiL74Pbo.27SrLs~Ca2.ogCu3.o4Oy (2223 phase) was determined as a function of temperature and oxygen partial pressure under the condition that Ca2PbO4 was not formed. It was also found that PbO evaporated from the 2223 phase about 700ยฐC in a low oxygen pressure range. Be
In the preparation of Bi2CaSr2Cu20 x particles with an 80 K superconducting phase by an ultrasonic spray-pyrolysis method the particle size was changed from submicrometre to micrometre size by changing the concentration of the metal nitrates in the starting aqueous solution. The volume mean diameter
