The resulting compound Ag₈SnS₆ in dimethylformamide medium

In the article listed the results of the study to obtain the compound of Ag8SnSe in dimethylformamide environment. The found that at 453 K and at pH = 4 obtained The compound of Ag₈SnS₆ in molar ratios AgNO₃/SnS₂ = 8:3, respectively. The individuality of the synthesized compounds was monitored by X-ray diffraction and DTA. According to X-ray diffraction data founds that the of 353-453 K resulting compound of Ag8SnSe mainly in the amorphous state. After heat treatment the intensity of the diffraction lines of Ag₈SnS₆ compounds are consistent with literature data. As a result of decoding, the following parameters of the orthorhombic lattice (space group Pna2₁): a = 15,3338; b = 7,5620; c = 10,7244 a . On the curve DTA of Ag₈SnS₆ compounds was found two endothermic effect. The endothermic effect detected at 445 K corresponds to the polymorphic conversion of Ag₈SnS₆. The endo-thermic effect at 1120 K corresponds to the melting temperature of Ag₈SnS₆ compound. According to the microstructural analysis (in the microscope of the company HITACHI TM 3000) found that at 453 K the formation of nanorods. The full nano-rods formation is observed at 453 K with a height of 4-7 |im, length 382-487 nm.
