An overview of synthesis and characterization of hydroxyapatite-zeolite composites for bone implant application

This review is focused on potential or already implemented applications of hydroxyapatite (HA)-zeolit composites as a human bones implant. The methodology is to synthesize and broaden the collection of literature published in the last ten years. The reviews are divided into two main sections, namely the synthesis and the characterization of HA-zeolite composites as candidates for human bone implants. Each article that has the same topic, whether it is about synthesis or characterization, is grouped, reviewed, and synthesized. The review generally covers important aspects of material testing and the results of the study. All reviewed literature shows that HA-zeolite composites can be produced by various methods. The chemical and morphological properties are suitable with the nature of human bones. The composites are also suitable as coatings on metal bone implants from Ti6Al4V and SS316L. In conclusion, HA-zeolite composites are potentially used as human bone implant material.
