Technical Field

[0001] The utility model relates to the technical field of hydroxyapatite preparation, in particular to a cooling and condensing device for hydroxyapatite preparation. Background Art

[0002] Hydroxyapatite is the main inorganic component of human and animal bones. It can form chemical bonds with body tissues at the interface, has a certain solubility in the body, can release ions that are harmless to the body, can participate in metabolism in the body, has a stimulating or inducing effect on bone hyperplasia, can promote the repair of defective tissues, and shows biological activity. It has been used in a variety of biomedical applications. Its preparation methods include: solid phase reaction method, mechanochemical ball milling method, hydrothermal synthesis method, chemical precipitation method, etc.

Therefore, we propose a cooling and condensation device for preparing hydroxyapatite. Utility Model Content
