7 Ceramic versus Polymer Membranes Although ceramic membranes have been known for centuries while polymer ones are relative newcomers, the latter are dominating the market. There are three good reasons for this, namely money, money and money (typically, ceramic membranes cost three to five times as much as polymer ones). Rough estimates are considering the material cost of US$2000/m2 of ceramic membrane versus US$400/m2 of a polymer one [57]. Accounting for higher fluxes and longer lifetimes of ceramic membranes, the difference becomes less dramatic: $60 versus $20 per unit of per­ meate volume, but still significant.

The prepared titanium nanofi­ bres, rods and surfaces fall under the definition of membranes mainly because these structures are porous and a fluid can pass through them. Conversely, the self-standing titania membranes suffer from poor structural stability [73]. They cannot be assembled into a module. When they are used, for example in catalytic reactions, they are suspended as particles in the reactor. The coating of supports with a titania layer is mainly performed via the sol–gel method, similar to silica coating.

Is good chemical and thermal stability. Alumina and silica are considered more thermally stable [82,83], whereas anatase titania and zirconia have a limited ther­ mal stability due to their relatively low phase transition temperature [84]. 12 shows the relative resistance of various ceramic materials to acids and bases. Generally, the more acidic a ceramic is, the greater is its resistance towards acids, and vice versa with bases. If the ceramic material is more base resistant, it is more prone to acidic attacks.
