Description

Application

• Enhancing Carbonate Content in Hydroxyapatites: Sodium carbonate is crucial in synthesizing carbonate-substituted hydroxyapatites, which are important materials in bone regeneration and dental applications. Recent research has focused on maximizing the carbonate content in these materials, highlighting the role of sodium carbonate in enhancing their structural and functional properties (Nowicki et al., Journal of Solid State Chemistry, 2021).

Biochem/physiol Actions
