INTRODUCTION Innovative metal/ceramic composites produced by melt infiltration of innovative ceramic preforms prepared by a freeze casting technique are examined in this study. These composites exhibit a characteristic hierarchical structure: On a mesoscopic length scale, lamellar domains with sizes up to several millimetres are observed (Fig. 1). The aim of the present study is to analyze the ...

High strength, toughness, and conductivity are among the most sought-after properties of flexible electronics. However, existing engineering materials find it difficult to achieve both excellent mechanical high conductivity. To address this challenge, study proposes a facile yet versatile strategy for preparing super-tough conductive organo-hydrogels via freeze-casting assisted solution substit...

Porous phyllosilicate-based ceramics were manufactured by freeze-tape casting from clays of different particle size and morphology in order to characterize their microstructure stress rupture changes before after firing. Three raw selected: HCR (77% Halloysite–10Å), KORS (29% kaolinite), KCR kaolin (98% kaolinite). These exhibited a monomodal distribution used prepare four slurries, three with ...

Surface area, permeability, and mechanical robustness are particularly crucial for porous ceramics utilized in filter catalyst support applications. Unfortunately, these desirable properties often inversely related to one another via porosity pore size, creating a serious challenge the optimization of materials. To address this challenge, we propose hierarchical composite, fabricated by freeze ...

Porous Cu bodies with complex shapes were fabricated by freeze-casting and vacuum sintering water-based CuO slurry. The sintered bodies showed no noticeable macroscopic defects and good shape tolerance. The interconnected pore tunnels were observed by electronic microscopy. The pore size became smaller and the porosity and volume shrinkage of sintered porous bodies decreased with the increase o...
