Li2ZrO3'ün Katı Hal Sentezi ve Prosesin Termokimyasal Modellenmesi

In the present study, the solid-state synthesis of lithium zirconate (Li₂ZrO₃), a promising high-temperature CO₂ sorbent, was investigated. The effects of calcination temperature and duration on the synthesis process were analysed, and the thermochemical modelling of the reaction was done to predict the optimal experimental conditions. Lithium carbonate (Li₂CO₃) and zirconium oxide (ZrO₂) were utilized as raw materials, and the reactions were performed under air atmosphere with temperatures ranging from 650°C to 1050°C. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses revealed that nearly pure Li₂ZrO₃ could be achieved at temperatures above 750°C for reaction durations of at least 2 hours. The findings also highlighted the formation of monoclinic-Li₂ZrO₃ at elevated temperatures. This study demonstrates the efficiency of the solid-state synthesis method for producing Li₂ZrO₃ and provides insights into the thermochemical behaviour of the process, facilitating its potential application in CO₂ capture technologies.
