Abstract

The compounds α-lead oxide (α-PbO) and β-lead oxide (β-PbO) were purchased from Merck co. and used for thermal investigations in laboratory. The compound was heated in a thermogravimeter at different temperature, from 25 to 400 °C. The used gas atmosphere was O₂. The received products were investigated by X-ray diffraction (XRD) technique. The received product Pb₃O₄ was confirmed by XRD. The textures of two different morphologies of α-PbO, β-PbO and the product Pb₃O₄ is investigated by scanning electron microscope (SEM) and transmission electron microscope (TEM) techniques.

Keywords
