The invention relates to a composite material that comprises at least one magnesium component, whereby the magnesium component consists of pure magnesium or a magnesium-calcium alloy or a magnesium-calcium-X alloy, whereby X is another biodegradable element. The composite material also contains at least one organic anti-infective agent having a solubility in water at room temperature of less than 10 grams per liter.

Bio-absorbable composite materials containing magnesium and magnesium alloys as well as implants made of said composites

A process for producing high-purity magnesium by distillation at reduced pressure, which includes providing an apparatus having a retort formed from a material inert with respect to magnesium and an upper region defined by two vertically spaced level lines, a condensation vessel having a lower region and an upper region extending into the upper region of the retort, wherein the retort and condensation vessel are coupled to one another by an opening arranged in the upper region of the condensation vessel; providing a magnesium-containing metal melt to the retort at a level below the gap; and heating and maintaining the upper region of the retort at a temperature above the boiling point of magnesium to fill the retort with steam, thereby delivering a high purity melt into the condensation vessel via the opening.
