abstract = {Three wet chemistry routes were used to synthesize
Ba0.99Zr0.8Y0.2O3-delta (BZY20) and to avoid the drawbacks
of the conventional mixed oxide route used for its
preparation. Pure samples were prepared using the Matrix
Trapping and Decomposition (MTD) and Polyacrylamide Gel (PG)
processes. The compound as a powder is thermodynamically
stable up to 1250 degreesC while the purity of the bulk of a
pellet can be maintained up to 1500 degreesC. An expected
increase of the lattice parameter (from 0.4193 (BaZrO3) to
0.4228 (1) nm (BZY20)) was observed confirming the
dissolution of yttrium in the barium zirconate structure.
BZY20 absorbs large amounts of water vapor (H/Ba approximate
to 0.19) and pellets can be sintered up to $95\%$ at 1500
degreesC for 10 h. (C) 2004 Elsevier B.V. All rights
