Efficient crystallization and extraction of lithium carbonate based on hair

This study primarily focuses on utilizing hair strands to achieve the crystallization of lithium carbonate, aiming to investigate the factors influencing crystal formation and volume variation by altering external conditions. To research the reason of crystallization, we have identified the following influencing factors: the direction of crystal growth, the temperature, the evaporation rate, selection of containers. The study ultimately revealed that the container material, solution temperature, evaporation rate, and crystal growth surface all influence crystallization and crystal volume.
