摘要

Abstract

The equilibrium distribution coefficients of 12 impurities (As

Zn) in phosphorus were obtained by measuring their effective distribution coefficients at zone travel rate of 3

and 20 mm·h

-1

in the purification process with vertical zone-melting technique.The results indicate that the method is reliable.The equilibrium distribution coefficients are below 0.3 except arsenic.
