“…The compressive strengths are high enough to preserve the geometry and dimensions of the finished products during processing and use. They are comparable to those of materials presented in similar studies [13,17,19,20]. The average porosity of the composites obtained ranged between 15% and 25%.…”

“…There were obtained cylindrical samples, 2 for each type of material, with a diameter of 16 mm and a height between 14 and 16 mm. Following the compaction of the cylindrical samples, to remove humidity, the batch of samples was dried in the open air at a temperature of T = 20-23 ºC, for 48 h. Afterwards, the samples were sintered [19] at a temperature of T = 1100 ºC in a Nabertherm type oven according to the following treatment cycle: heating from T = 40 °C to T = 1100 °C for 71 min, holding at T = 1100 °C for 30 min, followed by cooling from T = 1100 ºC to T = 40 °C for 90 min.…”

The paper presents the results of a study of the filtering capacity of some filters from ceramic composite materials made on laboratory installation. The filtration process involved applying a pressure gradient to the filter by means of a centrifugal pump from the filter installation. The ceramic composite materials used to make the filters have a bentonite-based matrix. To achieve the porous structure, the matrix was reinforced with SiC and Al2O3 ceramic powders and to control the pore size, additional Al metal particles were added. The stages of obtaining and characterizing the filters, respectively of testing their filtering capacity of the suspended particles from the rainwater are presented distinctly. In conclusion, the dependencies between a series of structural and geometric characteristics of the filtering capacity were established.

“…It could be found that they all had bulk density of 1.78-1.84g/cm 3 and open porosity of 39.4-39.9%. The deviations were very slight, which was different with the samples using mullite, zirconia and calcium carbonate as binder in Choi's study [11]. Whatever the sintering temperatures were, the weight did not change after the charcoal and phenolic resin were burnt out at relative low temperature.…”

“…Because ceramic filter should have high compressive strength, high porosity, large pore size and permeability. For bonding technique, mullite, cordierite, zirconia and glass are commonly used as inorganic binders [5,10,11].…”

“…At this stage, cracks are generated and transmitted through extension or deflection along the grain boundaries, while the corundum grains are broken. Porous ceramics [56], layered ceramics [57,58] and fiber composite ceramics [59] have similar displacement behaviors [60]. Figure 10(b) shows a representative load-displacement curve of fracture toughness.…”

Coal gangue is used to prepare flake nano-mullite with a molten salt method. In order to increase the utilization value, corundum composite ceramics were prepared from the nanomullite and alumina. The effect of particle size of the raw material size and the content of mullite on mechanical properties of the corundum composite ceramics was studied. It is found that the mullite with appropriate sizes can be filled in between the corundum grains, thus increasing the density of the samples. The mechanical properties were enhanced due to the variation in the crack propagation mode. The optimized sample exhibited flexural strength and fracture toughness of 263.7 MPa and 5.0 MPa•m 1/2 , respectively. Griffith fracture theory analysis results indicated that the critical crack size reached 173.9 μm and the fracture energy was 127.6 J/m 2. Coal gangue has realized deep resource utilization, and the mechanical properties of composite ceramics are higher than alumina ceramics prepared under the same conditions. Flake nanomullite contributes to mechanical properties.
