Strontium dialuminate (SrAl 4 O 7 ) can be synthesized by crystallization of amorphous spray‐dried precursors or solidification from the liquid. In this paper, SrAl 4 O 7 was prepared via the ethylenediaminetetraacetic acid precursor route. Differential thermal analysis, thermogravimetric, fourier transform infrared spectroscopy, and X‐ray diffraction (XRD) were used to characterize the precursors and the oxide powders derived. XRD analysis showed that single‐phase SrAl 4 O 7 was obtained from pulverized resin at a temperature of 1050°C for 2 h and SrAl 4 O 7 can be stable at least up to 1200°C. Single‐phase SrAl 4 O 7 was not obtained from the citrate acid route.
