The interaction coefficients for phosphorus have been determined in the Fe-P-i systems at 1600℃. The experimental technique is the same as described in the paper on the Fe-P systems which was reported previously. The measured systems are Fe-P-Si, Fe-P-Al, Fe-P-Ti, Fe-P-V, Fe-P-Cr, Fe-P-Co, Fe-P-Ni, Fe-P-Nb, and Fe-P-Mo. The experimental results show that the interaction coefficients for phosphorus with the elements in the fourth and fifth periods increase with the atomic number of the elements. The results obtained are summarized as follows : ε^<Si>_P=12.6±0.6(11.9±0.6) ε^<Al>_P=4.6±0.7 ε^<Ti>_P=-8±2 ε^V_P=-4.9±0.7 ε^<Cr>_P=-3.8±0.7 ε^<Co>_P=0.9±0.7 ε^<Ni>_P=0.7±0.7 ε^<Nb>_P=-5.4±1.2 ε^<Mo>_P=-0.4±0.7
