Beschreibung
Zusammenfassung:	The invention discloses a method for preparing an injectable bone repair material by virtue of an ultra-gravity process. The method is characterized by comprising the following steps: adding a calcium salt solution and a sulfate solution to an ultra-gravity reactor; and synthesizing alpha-calcium sulfate hemihydrate under hydrothermal conditions so as to prepare the injectable bone repair material. The alpha-calcium sulfate hemihydrate prepared by the method disclosed by the invention is controllable in grain size and morphology; and compared with normal alpha-calcium sulfate hemihydrate, mechanical properties, a degradation rate and biological properties are effectively improved.
