PbS microspheres have been synthesized in large scale by a hydrothermal route, in which tungstosilicate acid (TSA) is used. The obtained PbS microspheres have been characterized using X‐ray diffraction (XRD), transmission electron microscopy (TEM), Scanning electron microscopy (SEM) and X‐ray photoemission spectroscopy (XPS). Experiments show that Tungstosilicate acid plays an important role for the control of the morphology of PbS microstructures. An evolution process is described based on experimental facts.
