Used as a catalyst in organic synthesis reactions, particularly in polymerization and oxidation processes. Serves as a precursor in the preparation of calcium-containing nanomaterials and thin films via sol-gel and chemical vapor deposition methods. Employed in the formulation of lubricants and fuel additives to improve thermal stability and reduce metal surface wear. Applied in analytical chemistry as a complexing agent for the detection and separation of metal ions. Also utilized in research for developing bioactive coatings on medical implants due to calcium’s role in bone regeneration.
