摘要: Abstract The precursor powders of the Ba2Can−1CunO2n+1+δ (n=1, 2, 3) are prepared by sol-gel route. stability and thermal behaviour these oxides during vacuum calcination has been investigated. suitability obtained samples for synthesis Hg-based high-TC superconductors as well a preparative peculiarities their discussed.
