Tetracalcium phosphate (TTCP) is a highly bioactive calcium phosphate material known for its ability to promote rapid bone bonding and regeneration. It reacts with other calcium phosphates, such as dicalcium phosphate, to form hydroxyapatite in situ, closely mimicking natural bone mineral. TTCP is commonly used in self-setting bone cements, dental materials, and bone repair applications where fast hardening and bioactivity are required. We provide TTCP in various particle sizes to suit different biomedical and research applications.
