Fabrication and properties of cordierite–mullite bonded porous SiC ceramics

Effect of sintering temperature in preparation of granular ceramic filter

“…Bai et al reported that the increased sintering temperature from 1400 1C to 1450 1C resulted in the rapid decrease of porosity and flexural strength for the fabrication of cordierite-mullite bonded porous SiC ceramics [17]. Choi et al observed the morphological changes in mullite-bonded SiC ceramics with pore walls at various sintering temperatures ranging from 1400 1C to 1500 1C [16].…”

“…Many previous researchers investigated the effect of sintering temperature on the physical properties of SiC ceramic composites, such as linear shrinkage, porosity, thermal conductivity, and mechanical strength [15][16][17]. Bai et al reported that the increased sintering temperature from 1400 1C to 1450 1C resulted in the rapid decrease of porosity and flexural strength for the fabrication of cordierite-mullite bonded porous SiC ceramics [17].…”

On the elastic deformation properties of porous ceramic materials obtained by pore-forming agent method

“…This way, the entire pore size distribution is taken into account by improving the predictive accuracy for the elastic modulus [1,61,62]. Table 1 shows the porosity experimental data being used in this paper to set our model for reproducing porous microstructure and the values related to the experimental elastic modulus values [4].…”

Evaluating the Sintering Kinetics of Porous Sic Ceramics

“…The film decreases in thickness at 1300°C, which is probably attributable to the formation of tridymite from cristobalite as the material shrinks. A certain quantity of micropores is seen at 1350°C, which is due to the presence of gaseous oxidation products trapped in the layer of silicon formed as a result of oxidation [11]. During the firing of specimens at higher temperatures, the bond between the oxide film and the substrate became so weak that the oxide film shed under stress.…”
