Alpha calcium sulfate hemihydrate and preparation method thereof
The invention provides alpha calcium sulfate hemihydrate and a preparation method thereof, and relates to the technical field of medical biological materials. The method sequentially comprises the following steps: S1, recrystallizing; S2, carrying out autoclaved dehydration; and S3, drying and grinding, wherein the alpha calcium sulfate hemihydrate is prepared by the method. In the embodiment of the invention, the fluidity of the calcium sulfate bone repair material is improved by combining an aliphatic carboxylate assisted recrystallization method with an autoclaving method, the obtained product can be injected for 6 minutes at an extremely low water-powder mass ratio of less than 0.3, and the clinical minimally invasive injection is realized.
本发明提供了一种α半水硫酸钙及其制备方法,涉及医用生物材料技术领域。所述方法依次包括如下步骤:S1、重结晶;S2、蒸压脱水;S3、干燥研磨;所述α半水硫酸钙通过上述方法制备。本发明实施例中,通过使用脂肪族羧酸盐辅助重结晶法结合蒸压法改进硫酸钙骨修复材料的流动性,得到的产品能够在小于0.3的极低水粉质量比下实现长达6分钟的注射,实现临床上的微创注射使用。
