Microstructural Characterization of Porous Silicon Carbide Membrane Support With and Without Alumina Additive

Fabrication and properties of mullite-bonded porous SiC membrane supports using bauxite as aluminum source

“…[1][2][3][4][5][6], porous SiC ceramics have attracted more and more attention in recent years due to their great mechanical and chemical stability, large internal surface area, low thermal expansion coefficient, and high thermal conductivity, etc. [7][8][9].…”

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

“…However, the high cost of recrystallized SiC associated with the high sintering temperature requirement (4 2300 1C) and its relatively low strength have restricted its wide applications. Porous SiC supports can be fabricated through reaction bonding [11,12] and liquid-phase sintering [13,14] at low sintering temperatures. Investigations on the behavior of dense reaction-bonded SiC and liquid-phase-sintered SiC in corrosive solutions have revealed that residual Si and sintering additives are detrimental to the corrosion resistance of SiC ceramics [15][16][17][18].…”

Processing and properties of polysiloxane-derived porous silicon carbide ceramics using hollow microspheres as templates

“…Hence, these types of ceramics are finding many applications including the filtration of molten metals, filtration of particles from diesel engine exhaust gases, filtration of hot corrosive gases in various industrial applications, gas-burner media, membrane supports for hydrogen separation and light-weight structural components for high temperature applications. [1][2][3][4][5][6] Since the open and closed porosity, pore size distribution and pore morphology in porous ceramics is related directly to their ability to perform a desired function in a particular application, there is a need to control these characteristics in order to achieve these superior properties. [7][8][9] All these characteristics are in turn strongly influenced by the processing route and templates used for producing porous ceramics.…”
