Formation and Stability of Ferroelectric BaTi2O5

By / January 27, 2010

Volume 93 Issue 1, Pages 295 – 300 Na Zhu, Anthony R. WestPublished Online: Nov 23 2009 6:56PM DOI: 10.1111/j.1551-2916.2009.03393.x ABSTRACT BaTi2O5 (BT2) is thermodynamically stable over a very narrow temperature range between 1220° and 1230°C: a modification to the BaO–TiO2 phase diagram is proposed. This thermodynamic stability was shown by constructing a time–temperature transformation…

Use of Heat-Treated Water Treatment Residuals in Fly Ash-Based Geopolymers

By / January 27, 2010

Volume 93 Issue 1, Pages 272 – 278 Xiaolu Guo, Huisheng Shi, Warren DickPublished Online: Oct 20 2009 1:34PM DOI: 10.1111/j.1551-2916.2009.03331.x ABSTRACT Geopolymerization is a developing field that can beneficially use heat-treated water treatment residuals (WTRs) to create fly ash-based geopolymers. In this study, geopolymers made only from fly ash (FA) and from FA plus…
