- •
Porous Si3N4 ceramics were prepared by the self-organization method of alginate.
- •
The obtained porous Si3N4 ceramics possess high cell density of 58000 cpsi.
- •
The prepared Si3N4 ceramics possess interesting hierarchical pore structure.
- •
The obtained ceramics have highly ordered channels and well mechanical strength.
- •
The microstructure and properties of the sample can be effectively controlled.
