Formation of apatite oxynitrides by the reaction between apatite-type oxide ion conductors, La8+xSr2-x(Si/Ge)6O26+x/2, and ammonia (2009)
Journal Article
Orera, A., Headspith, D., Apperley, D. C., Francesconi, M. G., & Slater, P. R. (2009). Formation of apatite oxynitrides by the reaction between apatite-type oxide ion conductors, La8+xSr2-x(Si/Ge)6O26+x/2, and ammonia. Journal of Solid State Chemistry, 182(12), 3294-3298. https://doi.org/10.1016/j.jssc.2009.09.029

Following growing interest in the use of ammonia as a fuel in solid oxide fuel cells (SOFCs), we have investigated the possible reaction between the apatite silicate/germanate electrolytes, La8+xSr2−x(Si/Ge)6O26+x/2, and NH3 gas. We examine how the c... Read More about Formation of apatite oxynitrides by the reaction between apatite-type oxide ion conductors, La8+xSr2-x(Si/Ge)6O26+x/2, and ammonia.

Synthesis and characterisation of the quaternary nitride-fluoride Ce2MnN3F2-δ (2009)
Journal Article
Headspith, D. A., Sullivan, E., Greaves, C., & Francesconi, M. G. (2009). Synthesis and characterisation of the quaternary nitride-fluoride Ce2MnN3F2-δ. Dalton Transactions : an international journal of inorganic chemistry, 9273-9279. https://doi.org/10.1039/b908591b

Ce 2 MnN 3 F 2-δ has been synthesised via low-temperature fluorination of the ternary nitride Ce 2 MnN 3 . To the best of our knowledge, Ce 2 MnN 3 F 2-δ is the first quaternary nitride-fluoride to be reported. The reaction of Ce 2 MnN 3 with 10% F 2...

An investigation of the high temperature reaction between the apatite oxide ion conductor La9.33Si6O26 and NH3 (2009)
Journal Article
Kendrick, E., Headspith, D., Orera, A., Apperley, D. C., Smith, R. I., Francesconi, M. G., & Slater, P. R. (2009). An investigation of the high temperature reaction between the apatite oxide ion conductor La9.33Si6O26 and NH3. Journal of Materials Chemistry, 19(6), 749-754. https://doi.org/10.1039/b808215d

There is growing interest in the use of ammonia as a fuel in Solid Oxide Fuel Cells (SOFCs). However, the possible reaction between the electrolyte and ammonia, and its potential effect on performance, has received little attention. In this paper, we...
