Hydroxyapatite forming method, hydroxyapatite and application of hydroxyapatite

The invention discloses a forming method of spherical hydroxyapatite, hydroxyapatite and application of the hydroxyapatite. The forming method specifically comprises the following steps: uniformly stirring and mixing a calcium chloride aqueous solution and an ammonium dihydrogen phosphate aqueous solution, filtering to obtain a hydroxyapatite precipitate, and directly dispersing the hydroxyapatiteprecipitate into deionized water without washing to obtain a turbid liquid; and mixing the hydroxyapatite turbid liquid and an alginate aqueous solution to form slurry, then adding the slurry into ametal salt solution in a dropwise manner, solidifying the hydroxyapatite into gel balls, and drying and roasting to obtain the spherical hydroxyapatite. The preparation method is simple in process, and the prepared spherical hydroxyapatite is high in sphericity degree and strength and has wide application prospects in the fields of catalysis, adsorption separation and bioengineering. 本发明公开了一种球形羟基磷灰石的成型方法及羟基磷灰石和应用，具体为先将氯化钙水
