Magnesium-calcium refers to systems that combine magnesium and calcium, either as alloys or as part of related compounds. In materials science, the Mg-Ca binary system includes a magnesium-rich solid solution and intermetallic phases such as Mg2Ca. These materials are lightweight and have attracted interest for potential use in structural components and biomedical applications.

In alloy form, small additions of calcium to magnesium can modify the microstructure and influence mechanical properties. Potential effects include refined grain size, improved strength and hardness, and enhanced creep resistance, though higher calcium contents may reduce ductility and alter corrosion behavior due to intermetallic phases. Processing methods for Mg-Ca alloys commonly involve casting and extrusion to achieve desired shapes and textures.

Biomedically, Mg-Ca alloys are studied as candidates for biodegradable implants. The goal is to provide temporary support while gradually degrading in the body, ideally aligning with tissue healing rates. Calcium can influence degradation rate and biocompatibility, but hydrogen evolution and corrosion control remain challenges. Research uses surface treatments and alloying adjustments to tailor performance and safety for orthopedic and dental applications.

Dietary and consumer contexts also involve magnesium and calcium, which are essential minerals. Some dietary supplements combine magnesium and calcium to support bone health and metabolic functions. In such products, appropriate dosage and potential interactions depend on individual health, age, and dietary intake, and guidance from healthcare professionals is often advised.

Overall, magnesium-calcium encompasses metallurgy, biomedical materials, and nutritional contexts, reflecting the diverse ways these elements interact in technology and health.
