At this research, we analyzed the structural evolution, as well as the surface morphology changes, produced by thermal annealing on plumbonacrite layers obtained by the chemical bath deposition technique. For that, several replicas of chemically deposited plumbonacrite layers were thermal annealed in open-air atmosphere at the temperatures of 100, 200, 300, 400 and 500 °C, always for 30 min. The as-grown and thermal annealed plumbonacrite samples were studied by X-ray diffraction and Raman spectroscopy to identify the crystalline phases induced by the thermal annealing, beginning from hexagonal plumbonacrite, presenting modifications until convert into hydrocerussite, and finally at 500 °C, it is obtained a mixture of phases containing lead oxides. Scanning Electronic Microscopy images showed the evolution of the surface morphology. The results show that plumbonacrite transforms into hydrocerussite at an annealing temperature of 300−400 °C and to a combination of lead carbonate at 500 °C.

在这项研究中，我们分析了通过化学浴沉积技术在铅锌矿层上进行热退火而产生的结构演变以及表面形态变化。为此，将几个化学沉积铅铅矿层的副本在露天气氛中于100、200、300、400和500°C的温度下进行热退火，始终保持30分钟。通过X射线衍射和拉曼光谱研究生长和热退火的铅锌矿样品，以鉴定由热退火诱导的晶相，从六方铅锌矿开始，进行修饰直到转变为水陶粒，最后在500°C得到包含氧化铅的相的混合物。扫描电子显微镜图像显示了表面形态的演变。
