Accelerated decomposition under argon atmosphere was identified as the primary cause of higher mass loss (2.5 %), attributed to the intensified decomposition reactions promoted by the dynamic argon environment. In contrast, decomposition was suppressed in air flow (1.8 % mass loss), where CO<sub>2</sub> participation in the formation of CaCO<sub>3</sub> and CO<sub>3</sub><sup>2−</sup> species was confirmed. However, viscosity elevation in air-treated sample was observed due to progressive impurity accumulation.
