Macro-porous ceramics: processing and properties
Tatsuki Ohji,Manabu Fukushima +1 more
TL;DR: Porous ceramics are now expected to be used for a wide variety of industrial applications from filtration, absorption, catalysts, and catalyst supports to lightweight structural components as mentioned in this paper.
Journal ArticleDOI
Synthesis of Porous Ceramics with Complex Pore Structure by Freeze‐Dry Processing
TL;DR: In this paper, the pore formation mechanism was discussed in relation to the starting slurry concentration and sintering temperature, and pore structure was substantially affected by these effects.
Journal ArticleDOI
Strengthening and Toughening Mechanisms of Ceramic Nanocomposites
TL;DR: In this article, small, brittle particulate inclusions have been shown to cause crack-tip bridging at short distances behind the crack tip, and it is the latter that produces the very high fracture strength of the ceramic nanocomposite.
Journal ArticleDOI
Formation and photocatalytic application of ZnO nanotubes using aqueous solution.
TL;DR: The morphology of the products was found to be sensitive to the pH values and chemical bath temperatures, and the highest photocatalytic efficiency was observed at pH = 5.82.
Journal ArticleDOI
Synthesis of Porous Silicon Nitride with Unidirectionally Aligned Channels Using Freeze-Drying Process
TL;DR: In this article, a porous Si 3 N 4 matrix was synthesized using a freeze-drying process, where macroscopically aligned open pores contained fibrous grains protruding from the internal walls of the matrix.
