95% calcium-rich eggshell can make magnesium alloys stronger

Researchers used powdered eggshells to produce stronger, harder magnesium alloys, replacing conventional calcium materials.

美国研究人员已经证明，利用废料将蛋壳粉末转化为更坚固、更硬的镁合金，以此替代从矿石中开采的传统钙成分。

这项概念验证研究采用摩擦搅拌挤压法将蛋壳粉掺入镁中。该工艺在生产过程中即可生成钙质材料，无需单独的矿石加工步骤。

镁合金在汽车、航空航天和生物医学等行业有着广泛的应用。研究人员提出的方法提供了一种更经济、更节能的途径来改善其机械性能。
