“…The low compressive strength of reticulated porous ceramics can be enhanced by several methods; vacuum infiltration coating [5], dip coating [6], centrifuge coating [7], slurry rheology modification [8], multiple slurry coatings [9,10], and whisker-reinforcement coating [11] have all been used to improve the mechanical stability of these ceramics. However, in this study, the enhancement of compressive strength was confined to the optimization of a conventional replica method by tuning processing conditions; average particle size, binder, solid loading, and dispersant.…”

Recently, porous ceramics have received much attention from researchers because of their excellent thermal and chemical stabilities compared to their counterparts (such as porous polymers and metals), despite their inferior mechanical instability. Among the various types of porous ceramics, reticulated porous ceramics have significant industrial potential because of their synergistic high porosity and permeability. However, to the best of our knowledge, there is insufficient data on the processing conditions or preparing optimal reticulated porous alumina. Therefore, we prepared and characterized reticulated porous alumina specimens by controlling various processing conditions, namely average particle size, solid loading, binder, and dispersant. The data obtained were used to assess whether the compressive strength of the reticulated porous alumina could be enhanced and to discuss the potential of these materials for various applications.

“…To minimize the weak point, several approaches have been investigated to improve the compressive strengths of reticulated porous ceramics. For example, dip-coating [12], whisker-reinforcement coating [5], slurry rheology modification [13], multiple slurry coatings [14], centrifuge coating [15], and vacuum infiltration coating [16], have been introduced to enhance the compressive strengths of reticulated porous ceramics. The authors also previously reported that the compressive strength of the reticulated porous alumina can be improved by increasing the sintering temperature and/or number of alumina coating layers [17].…”

In recent years, porous ceramics have been increasingly developed owing to their high levels of high-temperature stability and chemical stability. These properties are far superior to porous polymers and porous metals. As a representative porous ceramic, reticulated porous ceramics have been fabricated for several decades owing to their overwhelmingly high porosity, which is usually above 90%. There are growing concerns about the environmental problems. However, the data on the preparation of low-cost and natural material-based reticulated porous ceramics are not enough. Therefore, the authors studied the preparations and characterizations of reticulated porous ceramics prepared using diatomite and kaolin, and compared them to typical reticulated porous alumina. The obtained data were used to determine whether the reticulated porous diatomite-kaolin composite can be practically used in non-hard loading conditions. The structural properties and dielectric breakdown strength of the reticulated porous ceramics were examined using scanning electron microscopy, mercury porosimetry, μ-computed tomography (CT), and standard test apparatus of dielectric breakdown voltage.

“…In recent years, various methods of temperature control coatings have developed, such as painting and brushing [7], plasma spray [8], sol-gel [9,10], anodizing [11], chemical vapor deposition [12], magnetron sputtering [13,14], and ion implanting [15]. Consequently, various temperature control coatings have been successfully prepared with different ratios of absorbance and emissivity (α s /ε).…”
