The effects of temperature on the conversion of Li₂CO₃ to LiOH in a Ca(OH)₂ suspension were investigated. Li₂CO₃ microplates were used as the Li source. The results showed that Li₂CO₃ was converted to LiOH via in situ ion-exchange and dissolution–precipitation routes. The formation of mixed Ca_xLi_2−2xCO₃ intermediate species confirmed that at 25 °C needle-like CaCO₃ was formed heterogeneously on the Li₂CO₃ surface via in situ ion-exchange. At 60–100 °C, isolated CaCO₃ agglomerates were formed homogeneously via dissolution–precipitation. Temperature increases accelerated the dissolution and conversion of Li₂CO₃ to LiOH, producing solutions with high [CO₃²⁻]/[Ca²⁺] ratios; this favored homogeneous precipitation of isolated CaCO₃ agglomerates.

研究了温度对Ca（OH）₂悬浮液中Li ₂ CO ₃转化为LiOH的影响。Li ₂ CO ₃微孔板用作Li源。结果表明，Li ₂ CO ₃通过原位离子交换和溶解-沉淀途径转化为LiOH。混合的Ca _x Li _{2−2 x} CO ₃中间物种的形成证实，在25°C下，针状CaCO ₃通过原位离子交换在Li ₂ CO ₃表面上异质形成。在60–100°C下，分离出的CaCO ₃团聚是通过溶解-沉淀均匀形成的。温度升高加速了Li ₂ CO ₃的溶解和向LiOH的转化，从而产生了具有高[CO ₃ ^2-- / [Ca ²⁺ ]比的溶液。这有利于分离出的CaCO ₃附聚物的均匀沉淀。
