文摘The equilibrium distribution coefficients of 12 impurities (As,Fe,Ca,Co,Al,Cr,Cu,Mg,Mn,Ni,Pb,Zn) in phosphorus were obtained by measuring their effective distribution coefficients at zone travel rate of 3,5,10,15,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.
