摘要
12 杂质的平衡分发系数(作为， Fe ， Ca ，公司，艾尔， Cr ， Cu ， Mg ， Mn ， Ni ， Pb ， Zn )被测量他们在地区旅行的系数 3 评估的有效分发在磷获得， 5 ， 10 ， 15 ，并且 20
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.
