Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ЭЛЕКТРОПРОВОДНОСТЬ -- РАСТВОРЫ ТВЕРДЫЕ -- ОКСИД ВИСМУТА -- ТЕМПЕРАТУРЫ ВЫСОКИЕ Аннотация: New solid solutions, Bi2 –x–yTmxNbyO3 +δ, with tetragonal and cubic structures have been synthesized in the Bi2O3–Tm2O3–Nb2O5 system, and their electrical conductivity has been measured at temperatures from 670 to 1020 K. The 1020-K conductivity of the tetragonal solid solution Bi1.8Tm0.15Nb0.05O3 +δ is comparable to that of Bi1.75Tm0.25O3, the best conductor in the Bi2O3–Tm2O3 system Полный текст |
