Elaboration and chemical corrosion resistance of tubular macro-porous cordierite ceramic membrane supports

Development and characterization of tubular composite ceramic membranes using natural alumino-silicates for microfiltration applications

“…Inorganic membranes are gaining a lot of interest in the recent years, thanks to the development of new types of inorganic membranes [28][29][30][31][32][33][34][35][36][37]. The inorganic membranes have excellent high thermal, chemical stability, mechanical resistance [8,13,[38][39][40][41][42][43], a longer life-time, ease of cleaning, a low thermal conductivity and a low dielectric constant [43,44]. Furthermore, these membranes are found to be able to resist corrosive highly acids and alkali media as well as to withstand high pressure applications.…”

Composite ceramic membranes from natural aluminosilicates for microfiltration applications

“…Most of the supports are generally manufactured from compounds such as alumina (Al 2 O 3 ) [18][19][20][21][22][23][24][25][26][27][28], cordierite (2MgO Á 2Al 2 O 3 Á 5SiO 2 ) [29][30][31]) and mullite (3Al 2 O 3 Á 2SiO 2 ) [32][33]. These materials have relatively elevated prices which significantly contribute to the cost of membrane modules for industrial applications.…”

Effects of B4C on the microstructure and phase transformation of porous SiC ceramics

“…Studies and application data have shown that ceramic membranes present some limitations when exposed in harsh environments, such as hot corrosive solutions; among which, gradual degradation of the mechanical property of porous membrane supports may result in the damage of membranes under operating pressures [4][5][6][7]. It suggests that the main phases in the support such as Al 2 O 3 , or the inter-granular phase used to facilitate the sintering of porous support, cannot tolerate acid or alkali corrosion.…”
