| Abstract [eng] |
This study investigates the synthesis of La₂₋ₓMₓMo₂O₉₋ₓ (M = Ca²⁺, Sr²⁺, Ba²⁺; x = 0.01–0.2) ceramics via a tartaric acid-assisted aqueous sol-gel method. X-ray diffraction (XRD) analysis was employed to determine the crystal structure and identify impurity phases in the heat-treated ceramics. The results indicate that as the ionic radius of the alkaline earth metal increases, the substitution limit of the corresponding element within the LAMOX system also increases. Differential scanning calorimetry (DSC) analysis further revealed that an increase in the substitution level leads to a decrease in the intensity of the phase transition. It is important to note that increasing lanthanum substitution in LAMOX ceramics decreases the intensity of the phase transition. However, when the concentration of impurity phases in the ceramic mixture becomes significantly high, the heat generated during the phase transition starts to increase again. |
