Acceptor doped BaTiO

Figure 10.15 Chemical difiFusivity isotherms for the (a) undoped and (b) acceptor (1.8 mol% Al)-doped BaTiOs. Data from Refs [13] and [16],...

Next, we will consider BaTiOs doped with a fixed amount (x) of acceptor impurities A on, for example, cation sites (generically denoted as Ac). Specifically, these are assumed to be trivalent substituting Ti or Aji, for example, Al i. The lattice molecule may then be written as ...
