Intensification of synthesis and examination of technological parameters influence on the properties and structure of Bi-(Pb)-Sr-Cu-Ca-O ceramics

Application of active technology factors (for example, the introduction of Bi2Sr2Ca2Cu3Oy, (2223) phase additive) and corresponding optimization of synthesis parameters of Bi(Pb)-Sr-Ca-Cu-O (BSCCO) ceramics have allowed reducing the time of oxide precursor sintering from 250 to 25 h. Conditions of positive influence of 2223 phase additives have been investigated. Intensification of BSCCO ceramics synthesis was the basic purpose, but the authors have deliberately conducted broader examinations of the influence of technological parameters on the properties and structure of this material. The complex of the obtained effects (similarly to the solution of an equation set with several unknowns) helps increasing the probability of exact comprehension of the system: technology - processes occurring under ceramics synthesis - phase composition and structure - properties of BSCCO
