Preparation and characterisation of positively charged porous ceramic membrane. (April 2015) - Deng, C.
Abstract : In this study, positively charged porous ceramic membrane was prepared through mechanical milling, isostatic pressing and subsequent high-temperature sintering. Combined with isostatic pressing technology and solid-state particle sintering, the positively charged porous composite ceramic membrane was prepared and the uniformly dispersed nano-yttria (Y2 O3 ) was used as the inorganic charged agent in the ceramic membrane. The length, outer diameter and inner diameter of tubular ceramic membrane were 7, 2 and 1·1 cm, respectively. The ceramic membrane possessed a large number of irregular pores with pore size of about 0·5 μm and uniformly dispersed spherical Y2 O3 nano-particles in the ceramic membrane surface, expecting to get a good surface electrical performance.
