Abstract

A process for the preparation of double sodium-chrome (III) fluoride pyrophosphate in solid polycrystalline state of general formula of NaCrPOF involves the use of melt of mechanical mixture of polycrystalline substances. The mechanical mixture of NaPOand (NH)HPOis ground in agate mortar, poured to platinum crucible (porcelain crucible) of 100 ml volume and homogenized for 1 hour at temperature of 900 °C, NaF (20 % weight %) is added to melt and hold at temperature of 950 °C for 1 hour, CrO(13-15 weight %) is introduced, homogenized at 1000 °C for 2 hours, crystallized in interval of 1000-800 °C for 24 hours. The obtained crystals are washed and dried at room temperature.
