Water-activated chemical current sources
Magnesium-based alloys containing gallium and thallium, used for water-activated chemical current sources, are produced by batching base components and melting charge in container. Stirring is performed by container rotation with the following melt crystallization. Produced ingot is squeezed from container and rolled as a plate of 0,4 mm thickness at the temperature of 4000oС. Gallium and thallium distribution homogeneity in the volume of produced ingot, which is measured by technology of inductive-connected plasma atomic emission determination of chemical composition, is ±0,1%.
Produced water-activated chemical current sources (WCCS) based on Mg-Ga-Tl electrochemical system are distinguished by long-tome storing within inactivated condition, and by high values of power density.
Water-activated chemical current sources are related to standby power supply and used in marine signaling devices, rescue equipment, at buoys, in geophysical equipment, meteorological balloons, in torpedoes and acoustic buoys.
