Özet:

 

The partial substitution of potassium atoms by strontium   atoms in initial matrix K33_{3}Fe22_{2}(PO4)34)3_{4})_{3} with formation of   complex phosphates K3−2x3−2x_{3-2x}Srxx_{x}Fe22_{2}(PO4)34)3_{4})_{3} (x=x=x  =   0.75, 1.0, and 1.25) was determined using a solid-state reaction method.   According to powder X-ray diffraction (XRD) data, the prepared phosphates   with x=x=x  = 1.0 and 1.25 crystallize in a cubic system (space group   P21P21{P2}_{1}3) and belong to langbeinite family compounds, while for the sample   with x=x=x  = 0.75 a mixture of langbeinite-type phase and a minor amount of   K33_{3}Fe22_{2}(PO4)34)3_{4})_{3} was obtained. The decreasing trend of   lattice parameter aaa with increase of Sr amount in the phosphate confirmed the   incorporation of strontium in the langbeinite-related structure. The thermal   analysis results indicate that the obtained langbeinite-related compounds   are stable upon heating and their melting points are higher than 1000   ∘∘^{\circ}C. It should be noted that the determined iron-containing   phosphates can be obtained at temperature lower than ∘∘^{\circ}C,   which creates a perspective for using them as matrixes for immobilization of   radioactive strontium.
