METHOD FOR REDUCING THE IMPURITY RESISTIVITY OF SODIUM

Patent · 13 August 1963

OSTI ID:4659460

Post, R F; Taylor, C E

The inherent resistivity of sodium, at cryogenic temperatures, can be reduced by clustering the impurity atoms within the crystal latiice structure of the sodium, thereby reducing the effective electron collision cross section and thus reducing the number of collisions between the electrons and such lattice imperfections. The clustering is effected by heating the sodium to a temperature approaching its melting point, and maintaining the temperature for a period of time ranging generally from two to six days. (AEC)
