Electrolytic Production of Calcium Metal

The resulting calcium-tin alloy served as the anode for the electrorefming cell, which employed a CaC~-CaF2 fused salt as the electrolyte. Calcium metal was electrorefmed at 8500 C with a current efficiency of 85 pct based on calcium metal recovered. The calcium metal analyzed 99.2 pct, which is purer than commercially produced calcium.

In situ resource utilization - Wikipedia

2  · In space exploration, in situ resource utilization (ISRU) is the practice of collection, processing, storing and use of materials found or manufactured on other astronomical objects (the Moon, Mars, asteroids, etc.) that replace materials that would otherwise be brought from Earth.. ISRU could provide materials for life support, propellants, construction materials, and energy to a spacecraft

Calcium - Wikipedia

Dietary Factors Influencing Zinc Absorption | The …

It also appears that the long-term use of calcium supplements has no effect on zinc status; Gaian women who were given 1000 mg calcium/d had plasma zinc concentrations similar to those of unsupplemented women (Yan et al. 1996). The calcium content of the diet may, however, affect zinc absorption from phytate-containing meals.
