Letter

Ceramic membranes, owing to their novel properties, are important materials widely used in separation, filtration, and catalytic reactions [1]. Ceramic membranes have several advantages over polymeric membranes such as better chemical and thermal stabilities, longer life, and better defouling properties. These properties have made ceramic membranes desirable for use in food, pharmaceutical and electronic industries, etc. [2]. Among several methods, the sol–gel approach is considered to be most practical one for the preparation of ceramic membranes because the smallest possible pore size is determined by the primary particle size in the colloid suspension [3]. Depending on the desired pore size of the membrane, the membrane precursor particles may be prepared by the sol–gel process [4]. The sol–gel process consists of a series of steps which are (i) hydrolysis of an organometallic compound, (ii) peptization, (iii) dipping, (iv) drying and (v) sintering. This technique allows high...
