Highly porous Si 3 N 4 with macroscopically aligned pores were prepared by the unidirectional freeze casting process using liquid N 2 as refrigerant. The increased sintering temperature had no obvious influence on the porosity, but significantly promoted β£ β β€-Si 3 N 4 phase transformation and the g
