Needle coke with high orientation was prepared using coal tar pitch through thermal polymerization and high-temperature calcining at different magnetic field intensities. The effects of magnetic field on the preparation of needle coke were studied. The relationship between structure and property of needle coke prepared under magnetic field was characterized by SEM, XRD and FT-IR analysis. The results indicated that the effect of magnetic field on the preparation of needle coke was positive, which could improve the ordered degree of needle coke, and its fibrous texture and the ordered degree increases with the increase of magnetic field intensities.
