Porous calcium hexa‐aluminate ( CA 6 ) ceramics were in‐situ synthesized by heated CaCO 3 and α‐ Al 2 O 3 in a NaCl ‐based salt at 1400°C for 3 h, and then characterized by X ‐ray diffraction ( XRD ), scanning electron microscopy, ( SEM ) and mercury porosimetry. The size and morphology of the CA 6 crystals and pores were gradually changed with the increase of NaCl addition in the raw material, indicating that the molten salt not only provided a liquid environment for synthesis of CA 6 , but also generated considerable pores.
