“…Such prepared skeletons are easier to infiltrate with a liquid alloy, and composites produced in this way are characterised by high properties, regardless of the infiltration pressure. At higher sintering temperatures for ceramic samples, infiltration pressure is more important because the open pores are more constricted, and, hence, greater pressure must be applied to fill them [ 54 , 55 ].…”

Ceramic injection moulding and gas-pressure infiltration were employed for the manufacturing of alumina/AlSi10Mg composites. Porous ceramic preforms were prepared by mixing alumina powder with a multi-binder system and injection moulding the powder polymer slurry. Then, the organic part was removed through a combination of solvent and thermal debinding, and, finally, the materials were sintered at different temperatures. Degrading the binder enabled open canals to form. The sintering process created a porous ceramic material consisting of alumina without any residual carbon content. During infiltration, the liquid metal filled the empty spaces (pores) effectively and formed a three-dimensional network of metal in the ceramic. The microstructure and properties of the manufactured materials were examined using high-resolution transmission electron microscopy, porosimetry, and bending strength testing. Microscopy observations showed that the fabricated composite materials are characterised by a percolation type of microstructure and a lack of unfilled pores. The research confirmed the diversified nature of the connection at the particle–matrix interface. It was observed that the interphase boundary was characterised by the lack of a transition zone between the components or a continuous transition zone, with the thickness not exceeding 30 nm. Thanks to their increased mechanical properties and low density, the obtained composites could be used in the automotive industry as a material for small piston rings and rods, connecting rods, or even gears.

“…Additionally, these results are similar to those in previous studies of reticulated porous alumina and reticulated porous diatomite-kaolin composites, indicating that reticulated porous zirconia is lightweight and has excellent compressive strength while also having adequate dielectric breakdown strength, enabling a wide range of industrial applications, such as dielectric materials. In summary, in a previous study, the authors manufactured reticulated porous zirconia which was sintered at 1600 °C at 45 PPI, with compressive strength of about 1.26 MP [30]. However, the authors determined that this compressive strength result was insufficient compared to the results of the other types of porous zirconia, such as porous yttria-stabilized zirconia [30,31], fibrous zirconia [32], and ultra-high-porosity zirconia [33], among others.…”

“…When reticulated porous zirconia was ball-milled for 0, 1, 4, and 8 h and sintered at 1480 °C with 45 PPI, the corresponding compressive strength outcomes increased to approximately 0.14, 0.87, 1.00, and 3.78 MPa. In summary, in a previous study, the authors manufactured reticulated porous zirconia which was sintered at 1600 • C at 45 PPI, with compressive strength of about 1.26 MP [30]. However, the authors determined that this compressive strength result was insufficient compared to the results of the other types of porous zirconia, such as porous yttria-stabilized zirconia [30,31], fibrous zirconia [32], and ultra-high-porosity zirconia [33], among others.…”

In recent years, there has been growing interest in porous ceramics in many research areas given their superior thermal and chemical resistance capabilities, unlike porous metals and porous polymers. Among the various types of porous ceramics, reticulated porous ceramics can offer significant industrial potential due to the low density and high permeability of these materials. However, industrial applications are somewhat rare owing to the rather low compressive strength of reticulated porous ceramics compared to other types of porous ceramics. Although there have been many studies related to reticulated porous ceramics, few have focused on reticulated porous zirconia. Therefore, the aim of this study is to determine how to obtain a high compressive strength in reticulated porous zirconia by optimizing the process conditions of the solid loading level and the particle size and by using additives in a zirconia slurry sample. Furthermore, the authors assess the effects on the microstructure and compressive strength of multiple slurry coating, specifically from one to three. In conclusion, the effect of varying these various process conditions on the resulting improvement in compression strength was investigated, and the compression strength of reticulated porous zirconia was significantly increased from 0.14 to 9.43 MPa. The characteristics investigated include the pore characteristics (pore density, pore size and pore structure), the sintering behavior (linear shrinkage), the mechanical properties (compressive strength), and the dielectric properties (dielectric breakdown strength).

This research aims to create a new innovation in traditional ceramics through high-temperature firing. Thisinnovation in ceramic teapots uses clay from Pagerjurang, Klaten, and central Java. Pagerjurang village is one of the producers of traditional ceramic products in Indonesia. The clay found in Pagerjurang can only be fired at temperatures of 750 ◦C - 900 ◦C, which classifies it as low-quality clay. This research uses a qualitative exploratory method by experimenting with the clay's quality and artistic value. Mixing 25% silica with the clay could then be fired at 1100 ◦C, enabling the glazing technique. This innovation could increase the quality of traditional ceramic products from Pagerjurang. The new products are expected to be able to be used as examples to improve the quality of conventional teapot products and, at the same time, increase the welfare of the ceramic artists of Pagerjurang.
