X-ray study of the reaction products in obtaining lead telluride by a low-temperature iodide method

Results from X-ray studies of the products of the reaction in obtaining lead telluride by the iodide method are presented. It is demonstrated that PbI2 condenses at the flow of the inert gas on the cool parts of the reactor at the isothermal annealing of the synthesized material. This is in agreement with the assumption about the self-alloying of PbTe as a result of the higher solubility of Pb under conditions of dissolving PbI2 in lead telluride. (author)
