Calcium phosphate (CaP) is an inorganic ceramic compound that exists in multiple forms, most commonly as hydroxyapatite, which closely resembles the mineral composition of bone and teeth. It is widely used in biomedical applications where biocompatibility and osseointegration are critical, and is also applied in environmental remediation and industrial catalysis. Engineers select CaP ceramics primarily for their ability to bond directly with living bone tissue, their chemical stability in physiological environments, and their role as a bioresorbable material that can gradually resorb and be replaced by natural bone during healing.
