Evaluation of the efficiency of sintering of porous ceramic materials
Refractories and Industrial Ceramics, 1997Refined estimates of the efficiency of sintering were obtained using various structural models of ceramic materials. The most precise method is based on a special model developed by the author for the structure of powdered materials and an approximation according to which the Voronoi polyhedra are assumed to remain unchanged on decreasing the porosity ...

A Technique for the Preparation of Porous Ceramic Materials by Gelcasting Method
Advanced Materials Research, 2010A technique for the preparation of porous ceramic materials by gelcasting mothod is studied using a water-soluble epoxy resin combined with a amine hardener. The increase in the volume and rheological behavior of slurry , TGA and DSC of the green bodies are investigated. The influence of solid content on the relative density, the cell size distribution

Highly porous ceramic materials based on coarsely dispersed αAl2O3
Perspektivnye MaterialyThe synthesis of highly porous ceramic materials for catalytic converters based on coarse-dispersed αAl2O3 was carried out using a combination of compaction and thermochemical synthesis methods with the participation of active ultrafine binders. Using XRD and SEM methods, it was established that the morphology of the synthesized material includes the ...

Propagation of Terahertz Radiation in Porous Polymer and Ceramic Materials
AIP Conference Proceedings, 2005In this work we investigate the propagation of terahertz radiation through polyurethane foam and porous alumina ceramics to understand the effects of structure on the optical properties of these materials at terahertz frequencies. A terahertz time domain system with a GaAs photoconductive emitter and a ZnTe electro‐optic crystal was used to generate ...

The sound absorption characteristics of particulate porous ceramic materials
Applied Acoustics, 1994Abstract The particulate porous ceramic materials fabricated by sintering were found to be effective in sound absorption treatment. The sound-absorbing features are somewhat different from those of ‘glasswool’ which is the most typical, fibrous, sound-absorbing material.
