Preparation method of degradable zinc-calcium compound composite material

The invention relates to a preparation method of a degradable zinc-calcium compound composite material. According to the preparation method, pure zinc melt is pressed into gaps among zinc-calcium compound CaZn2 particles which are stacked together and have high calcium content, and calcium elements on the surface layers of the CaZn2 particles are diffused into the zinc melt under the high-temperature action of the zinc melt and react with zinc to generate a zinc-calcium compound CaZn13 with low calcium content and the like. The composite material completely composed of the zinc-calcium compound is obtained. High pressure (50MPa) does not need to be used in the preparation process, zinc powder and other materials easy to explode are not used either, and the obtained composite material shows excellent Ca and P element deposition inducing capacity and shows excellent cell activity on L-929 cells. 本发明为一种可降解锌钙化合物复合材料的制备方法。该制备方法通过将纯锌熔体压入堆积在一起的具有高钙含量的锌钙化合物CaZn2颗粒间的缝隙中，CaZn2颗粒表层的钙元素在锌熔体的高温作用下扩散进入锌熔体中并与锌发生反应生成具有低钙含量的锌
