Coralline hydroxyapatite and preparation method thereof

Abstract

A coralline hydroxyapatite having a pore size of 30 μm to 1300 μm, a porosity of 50% to 70%, and a conversion rate of 50% or more, and a preparation method are disclosed. The preparation method comprises: soaking pretreated corallite in a cutting protective agent, and then cutting to obtain cut corallite, and screening for cut corallite that meets a cutting size requirement to obtain an acceptable product of cut corallite; fully soaking the acceptable product of cut corallite in a phosphate solution, and performing a hydrothermal exchange reaction to obtain the coralline hydroxyapatite; wherein the cutting protective agent is a solution containing a polyol. The preparation method can significantly improve the cutting efficiency, broaden the cutting specifications and sizes, and significantly improve the yield of acceptable product, especially the yield of acceptable small-size products, which further broadens the application range of artificial bones.
