An overview of the current state of theoretical studies of close-packed systems of hard spheres is presented. A description of the main models of regular and random dense packings of rigid spheres is given. ...
A refined analytical method is proposed for determining the average (hydraulic) radius of a capillary on the basis of a three-dimensional model of the porous structure of materials, taking into account ...
An overview of the directions for improving the technological processes of foam glass production using mathematical modeling over the past 15 years is presented. The developments of leading scientists ...
The porous structure of polymer and gypsum molds is analyzed. Models of their structure are proposed on the basis of the model of chaotically located spheres and the theory of percolation. The calculation ...
... zirconium dioxide into the foaming mixture leads to a change in the macrostructure of the foam glass and an increase in the average pore size to 2.5 mm. Nano-sized ZrO 2 reduces the melt viscosity during ...
Flat membrane contactors have been obtained, which are ceramic disk micro-filtration membranes with a Co 3 O 4 layer applied. Such characteristics as the layer thickness, pore size distribution were ...
On the example of ordered packages of bulk media? balls considered a model of their structure? with cells in the form of conditionally cut (quasi-faceted) parallelepipeds, the vertices of which are located ...
The microstructure of gypsum and polymer molds for slip casting of ceramic products has been investigated. The analysis of the microstructure of porous molds showed that gypsum molds have a more finely ...
The behavior of water in model glasses of Na 2 O - B 2 O 3 - SiO 2 systems has been studied by IR spectroscopy. and K 2 O - B 2 O 3 - SiO 2 . It has been established that hydroxyl groups ...
The effect of various pore-forming additives in the form of recycled Claus catalyst, gypsum and coke on the physical and technical characteristics and permeability of the structure of corundum ceramics ...
It is shown that the introduction of up to 15% pyrite cinders into ceramic masses significantly improves the frost resistance of tiles, while water absorption decreases disproportionately to frost resistance. ...
The characteristics of microporous borosilicate glasses are presented. Recommended for the production and use of glass with an optimal poredistribution. Tab. 2, ill. 3, bibliography: 2 titles.
