| Popis: | The interaction in the molten systems M I PO 3 -M III 2 O 3 - M I NO 3 ( M I Cl) ( M I – Na, K; M III – Al, Fe, Y, Bi) was investigated at molar ratios P/ M III =1 or 3 at the temperatures 400 °C (for M I NO 3 ) or 810 °C (for M I Cl). Formation conditions of complex phosphates M I 3 M III 2 (PO 4 ) 3 and M I 3 M III (PO 4 ) 2 ( M I – Na, K; M III – Al, Fe, Bi) were established. It was shown that the crystal size of obtained phosphates can be controlled by using different salt melts. The synthesized compounds were characterized using powder X-ray diffraction, Fourier transform infrared spectroscopy, Optical microscopy and Scanning electron microscopy with Energy-dispersive X-ray spectroscopy. Differential thermal data for Na 3 Bi(PO 4 ) 2 and Na 3 Fe(PO 4 ) 2 showed congruent and incongruent melting, respectively. |
