Effects of CeO2 addition on the properties of cordierite-bonded porous SiC ceramics

Properties of multiple oxide‐bonded porous SiC ceramics prepared by an infiltration technique

“…and the strength of the completely dense material (σ 0 ) and the value of constant (b) were calculated. The values of flexural strength obtained in this work are comparable with the reported values in literature [37][38][39]. 20 Bai et al reported variation in flexural strength between 15.6 and 54 MPa, porosity ~37-53 vol%, σ 0 = 1237.04 MPa and b = 8.16 for cordierite-mullite-bonded porous SiC F I G U R E 2 Pore size distribution patterns of multiple oxidebonded porous SiC ceramics sintered at different temperatures F I G U R E 3 XRD patterns of porous SiC ceramics showing multiple oxide phases ceramics.…”

“…We observed that the normalized pressure drop increased with superficial fluid velocity for the ceramics at any given porosity and the pressure drop further increased with the decrease in porosity from 37 to 33 vol%. 39 These data thus indicate that Darcian permeability coefficient values of the porous SiC ceramics investigated in the present work are improved compared to the reported data. 29 The permeability coefficient k 1 and k 2 were evaluated from the fitting constant of the curves of Figure 5.…”

In-situ synthesis and properties of cordierite-bonded porous SiC membrane supports using diatomite as silicon source

“…Thus, cordierite is chosen as an extraordinary phase to fabricate porous SiC ceramics. Liu and coworkers [15] prepared cordierite-bonded porous SiC ceramics from SiC, Al 2 O 3 and MgO via in situ reaction bonding technique in air, which demonstrate superior mechanical properties and thermal shock resistance. Zhu et al [16] processed cordierite-bonded porous SiC ceramics in air from SiC, clay, talc and Al 2 O 3 in reaction bonding technique which obtained high porosity ranged from 28% to 60%.…”

Synthesis of mullite bonded porous SiC ceramics by a liquid precursor infiltration method: Effect of sintering temperature on material and mechanical properties

“…Bonding of SiC can be done at low temperatures by use of different oxide and non-oxide secondary phases. They include silica [7][8][9], mullite [10][11][12][13][14], cordierite [15][16], silicon nitride [17], etc. Choice of mullite as a bond for SiC has many advantages.…”
