Diatomite-based porous ceramics with high apparent porosity: Pore structure modification using calcium carbonate

Ceramics International, 2019
High apparent porosity ceramics have a wide range of applications in chemical, environmental, and automotive sectors as reactors, absorbers, and cleaning devices due to their large specific surface area and excellent permeability for fluids.

Recycling of waste red mud for fabrication of SiC/mullite composite porous ceramics

Ceramics International, 2019
SiC/mullite composite porous ceramics were fabricated from recycled solid red mud (RM) waste. The porous ceramics were formed using a graphite pore forming agent, RM, Al(OH)3 and SiC in the presence of catalysts.

Strength of Highly Porous Ceramic Electrodes

Journal of the American Ceramic Society, 2011
Highly porous ceramics are critical components of Solid Oxide Fuel Cells. Nevertheless, their mechanical properties are poor and not fully understood. Herein, Discrete Element simulations are used to quantitatively assess the relation between the particulate microstructure of highly porous ceramics and their mechanical properties.

Ceramic porous materials with catalytic properties

Perspektivnye Materialy, 2019
Undoubted leadership among catalytic materials for the purification of exhaust gases is occupied by composite cermets. Creation of catalytic materials for gas purification indicates that the main problem is partial or complete replacement of rare earth metals in their composition.

A novel composite phase change material with paraffin wax in tailings porous ceramics

Applied Thermal Engineering, 2019
A new composite phase change material (CPCM) is developed for thermal energy storage applications. The CPCM is fabricated by spontaneous melt infiltration of paraffin wax into a porous ceramic carrier made from industrial waste-iron tailing with a foam ...

Porous PZT ceramics for receiving transducers

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2003
PZT-air (porous PZT) and PZT-polymer (polymer impregnated porous PZT) piezocomposites with varying porosity/polymer volume fractions have been manufactured. The composites were characterized in terms of hydrostatic charge (dh) and voltage (gh) coefficients, permittivity, hydrostatic figure of merit (dh.gh), and absolute sensitivity (M). With decreasing

Preparation of homogeneous mullite fibrous porous ceramics consolidated by propylene oxide

Ceramics International, 2019
Silica sol, one of the most commonly used binders in the fabrication of fibrous porous ceramics, can diffuse as the solvent evaporates during the drying stage, leading to an uneven structure of ceramics.
