- •
Diatom frustules for the first time were used as Si precursor for synthesis of porous mullite with fibrous pore structure.
- •
The porous ceramics featured relative high porosity of 60% without using any porogen.
- •
The porous ceramics featured negligible sintering shrinkage of 1% when sintered at 1500 °C for 3 h.
