The subsolidus region of the BaO-La2O3-V2O5 phase diagram has been redetermined. Previously reported binary phases of LaVO4, La8V2O17, La3VO7, BaLa2O4, Ba3V2O8, Ba2V2O7, Ba3V4O13 and BaV2O6 have all been confirmed. The ternary phases Ba2LaV3O11, Ba3LaV3O12 and Ba3La40V12O93 have also been confirmed. The new phase "BaLa10V4O26" has been synthesised for the first time and is reported here along with the amended phase diagram. The previously omitted phase of La1.42V0.58O3.58 has also been included and reasons for this are cited. The diagram is shown for two temperatures (1000 and 600 degreesC) due to the low melting point of V2O5-rich compounds. (C) 2002 Elsevier Science Ltd. All rights reserved.
