Jf. Marucco et al., SYNTHESIS AND ELECTRICAL-PROPERTIES OF SOLID-SOLUTIONS BANB1-XTIXO3 WITH 0-LESS-THAN-X-LESS-THAN-0.8, Journal of alloys and compounds, 262, 1997, pp. 454-458
The cubic perovskite BaNbO3 has been prepared in sealed ampoules from
mixtures of Ba5Nb14O15 and Nb. Solid solutions BaNb1-xTixO3 have been
prepared from mixtures of BaTiO3 and BaNbO3 fired at 1300 degrees C un
der purified argon flow. Between O < x < 0.7, electrical resistance me
asurements from 4.5 K to 250 K indicate that these compounds behave as
metals. For x = 0.8, a metal-non-metal transition occurs, not explain
ed by semiconducting behaviour. (C) 1997 Elsevier Science S.A.
