Description

Application

• Local concentration controls the hydrate phase of calcium oxalate.: This research demonstrates how adjusting the titration rate of calcium solution and stirring speed can influence the formation of different hydrate phases of calcium oxalate. Such control is critical for applications requiring specific crystal forms, such as in bioceramics and industrial processes (Wang et al., 2024).
