Stabilization of monoclinic SrAl{sub}2O{sub}4 trough the formation of solid solutions of the type SrAl{sub}(2-x)B{sub}xO{sub}4

摘要

The aim of this work is to study the synthesis conditions for preparing SrAl{sub}2O{sub}4 at low temperature and its stabilization as a monclinic form by synthesis of solid solutions of the type SrAl{sub}(2-x)B{sub}xO{sub}4 (x = 0, 0.1, 0.2, 0.3). The addition of boron can reduce the synthesis temperature of SrAl{sub}2O{sub}4 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.
