Influence of water molar ratio on fabrication of silica ceramic membranes via sol-gel dip-coating method

Ceramic membranes are an inorganic membrane that received great attention as it overcome the limitation of polymeric membrane. The silica ceramic membrane can be used in gas separation as it able to work at elevated temperature and in chemically aggressive environment. This work is conducted to st...
