Used in biomedical applications for bone and dental implants due to its biocompatibility and similarity to natural bone mineral. It promotes bone regeneration and integration with surrounding tissues. In tissue engineering, it serves as a scaffold for the growth of new bone cells, aiding in the repair of damaged tissues. Also employed in coatings for orthopedic and dental implants to enhance osseointegration. Utilized in drug delivery systems for controlled release of therapeutic agents. In cosmetics, it acts as an abrasive and remineralizing agent in toothpaste and oral care products for effective cleaning, polishing of teeth, strengthening enamel, and preventing decay. Additionally, it finds use in water treatment for removing heavy metals due to its adsorption properties.
