Abstract The ternary compound Zn_55.24Al_18.86Zr_25.9 was prepared by equilibrated alloy method and examined by X-ray diffraction, scanning election microscopy (SEM). Crystal structure of the compound was successfully refined by the Rietveld method. The reliability factor for Rietveld refinement is R_p=7.15%,R_wp=9.56%.The compound crystallized in a cubic structure with space group p4/mmm, lattice parameters a=b=4.070 803 Å, c=4.073 669 Å. In the structure, Zr atoms occupied the 1a site, some Zn atoms occupied the 2e site, while the other Zn atoms and Al atoms were in the 1c sites. Finally, the rationality of the obtained structure was verified by theoretical calculation.

Key words： Zn-Al-Zr alloy Rietveld method theoretical calculation
