Abstract

Porous Si₂N₂O ceramics strengthened by directional β-Si₃N₄ are fabricated by direct ink writing technique and seeding method. Slurries prepared with different contents of β-Si₃N₄ grains exhibited superior printing behavior. The degree of orientation of β-Si₃N₄ grains increased with the increase of grains content. The mechanical properties of the porous Si₂N₂O ceramic are effectively improved by interspersed β-Si₃N₄ grains and present anisotropy. This novel strategy provides a reference for fabricating high-performance anisotropic complex structure ceramics.
