| abstract |
A Porous ceramic filter and its method of production are disclosed. The ceramic filter has at least one porous layer (or skin) made of a binder formed of a cured ceramic powder and a preceramic or pyrolyzed ceramic precursor optionally containing a source of zirconia. In some embodiments, the binder is formed of the zirconia source only. The presence of the zirconia gives a skin with good mechanical strength and corrosion resistance to both acidic and basic solutions. |
