N2  - Indium is transferred by the tartaric acid in thestrong complex in aqueous medium. Then the selenizing solution (solution ofselenium on sodium tetraborate) is added. The voluminous sediment of yellowcolor turns out. Composition of the determined by differential thermal analysisand electron microprobe analysis. The qualitative analysis of this sediment hasshown the presence of indium and selenium. In various experiments are producedsediments of different colors when medium pH changes. The set of experimentshas been carried out to specify color change and hydrogen ions concentrationimpact. ThisFeIn2Se4compound forproduction FeSO4x7H2Ois mixed with In2Se4inthe molar ratios 2:3 (FeIn2Se4)with the presence of acetate acid(pH=7-3), at293-353 K in aqueous medium. In organic medium test within 10 hoursat 413– 443 K totemperature remains in the furnace. Phase analysis ofFeIn2Se4is studiedusing the X-ray powder diffraction (XRD) andchemical analysis. The compoundFeIn2Se4crystallized inhexagonal singoniya a=4.012 Å, c=39.21Å. Morphological investigations have been performed usingscanning electron microscopy (SEM). Optical absorption is measured using aspectrophotometer, IK spektr analysis on the basis of the spectrum, whichhas been read from the dispersed solution ofFeIn2Se4iscalculated. Differential thermalanalysis (DTA) ofFeIn2Se4compoundis observed one endothermic effect. In the system Tg=1158K aqueousmedium,Tg=1123Korganicmedium endothermic effect corresponds to themelting point of the combination. In this iron indium selenideefficiency is 92.2 %.
