The crystal structure of the subvalent nickel—lead sulfide, which has been described previously as Ni60Pb9S31, was established and the composition of this sulfide was refined based on powder X-ray diffraction data. The true Ni151.5Pb24S92 composition of this compound was confirmed by the EDX techniques. The temperature range of stability of this compound (490—578 °C) was refined by differential thermal analysis. In the search for analogs, the triangulation of the Ni—Pb—Se and Ni—Pb—Te systems at 540 °C was carried out for the first time. No new ternary phases were detected. [ABSTRACT FROM AUTHOR] |
