LOW-α RAY HIGH-PURITY ZINC AND METHOD FOR PRODUCING LOW-α RAY HIGH-PURITY ZINC

摘要

PROBLEM TO BE SOLVED: To provide low-α ray high-purity zinc which allows zinc material with lower lead concentrations and less α rays release to be produced, and a method for producing low-α ray high-purity zinc.SOLUTION: The low-α ray high-purity zinc has a lead content of less than 0.01 ppm, and an α-ray count of 0.001 cph/cmor less.SELECTED DRAWING: Figure 1
