Stabilization of monoclinic SrAl2O4 trough the formation of solid solutions of the type SrAl2-xBxO4

The aim of this work is to study the synthesis conditions for preparing SrAl2O4 at low temperature and its stabilization as a monclinic form by synthesis of solid solutions of the type SrAl2-xBxO4 (x = 0, 0.1, 0.2, 0.3). The addition of boron can reduce the synthesis temperature of SrAl2O4 because it can provide a liquid medium and increase the diffusion rate and also it can replace the Al (III) ions in the tetrahedral sites of the structure and the distortions caused because of its low ionic radius compared to the aluminium one, could explain the observed reduction in synthesis temperature.
