摘要：

The system KF-A1F(3) was reinvestigated precisely by differential thermal analysis, X-ray diffractometry, and visual observation. All of the samples for the present investigation were prepared by solution synthesis. The results verified the existence of 2KF . AIF(3) (K(2)AIF(5)) and KF . 4AIF(3) in the phase diagram; both compounds were orthorhombic, The cell parameters of the compounds mere, respectively, a = 10.87 +/- 0.03 Angstrom, b = 10.36 +/- 0.01 Angstrom, c = 7.83 +/- 0.03 Angstrom, and a = 7.89 +/- 0.01 A, b = 7.57 +/- 0.01 Angstrom, c = 6.94 +/- 0.01 Angstrom . KAIF(4) was confirmed to melt congruently at 575 degrees +/- 2 degreesC by careful examination.
