The physicochemical properties of semiconducting BaTiO3 doped with TiB2, Ti
C, TiN, ZrN, BN, and AlN have been studied using thermogravimetry, XRD anal
ysis and electron microscopy. When the above dopants are added, compounds a
re formed which influence redox reactions, which proceed during the synthes
is of (Ba, Y)TiO3 ceramics, and allow the temperature range of reduction to
be extended. (C) 1999 Elsevier Science Limited. All rights reserved.
