[0002] Hydroxyapatite is currently recognized as a new type of ceramic material with good biocompatibility and osteoconductivity, that is, biosoluble. It is the main component of human and animal bones, teeth, and tusks. With the advancement of science and technology and the continuous improvement of people's understanding, many research results show that hydroxyapatite is a non-toxic, non-carcinogenic, non-side effect, and biocompatible bioactive material. People have also found that hydroxyapatite has solid alkaline properties and strong polymer exchange capacity. Therefore, it is widely used in catalytic carriers and polymer fields (industrial water, domestic water defluorination).
