The use of concentrated solar energy in processing ceramic materials is an attractive route to obtain these materials with low CO₂ emissions. In this work, nanostructures of monoclinic zirconia (m-ZrO₂) were obtained using concentrated solar energy provided by the IER-UNAM solar furnace as a heat source. In the first stage of the process, a Zr/O/C complex was obtained by sol-gel method at a temperature of 120 C using zirconium n-propoxide and sorbitol as precursors reagents. This complex was used in a second stage to obtain m-ZrO₂ by heating it at a temperature of 1200 C for one hour in air atmosphere. This last stage was performed in a solar furnace. Samples were analyzed by characterization techniques: FT-IR, TGA/DSC, XRD, TEM, and SEM confirming the formation of nanostructures of zirconia in monoclinic phase.

在加工陶瓷材料中使用集中太阳能是获得具有低CO ₂排放量的这些材料的有吸引力的途径。在这项工作中，利用IER-UNAM太阳炉提供的集中太阳能作为热源，获得了单斜晶氧化锆（m-ZrO ₂）的纳米结构。在该方法的第一阶段，使用正丙醇锆和山梨糖醇作为前体试剂，通过溶胶-凝胶法在120℃的温度下获得Zr / O / C络合物。该络合物用于第二阶段以获得m-ZrO ₂通过在空气气氛中将其在1200℃的温度下加热一小时。最后阶段在太阳能炉中进行。通过表征技术对样品进行分析：FT-IR，TGA / DSC，XRD，TEM和SEM证实了单斜晶相中氧化锆的纳米结构的形成。
