Apatite is a common mineral group that is composed of calcium phosphate, with the general formula Ca5(PO4)3(F,Cl,OH). It is commonly found in sedimentary, igneous, and metamorphic rocks and is a major component of tooth enamel and bone in vertebrates. Apatite has a wide range of applications in various industries including the production of fertilizers, ceramics, and the development of phosphate-based materials for the biomedical field. Research on apatite focuses on understanding its crystal structure, properties, and behavior in different environments, as well as its potential uses in advanced technologies and medical applications.
