A sequence of operations for the manufacture of quartz glass samples from natural highly enriched raw materials and synthetic silicon dioxide is described and implemented. The main attention is paid to the purification of raw materials and maintenance of the finishing regime during the glass manufacturing process. It is shown that it is preferable to use synthetic raw materials to obtain quartz glass with a low value of internal friction.

With the help of morphological and electron probe microanalysis, it was found that one of the defects of glass melt in the production of continuous glass fiber, causing increased breakage, are inclusions of molybdenum disulfide, which is formed as a result of sulfate corrosion of electrodes. The source of defects can also be salt deposits, condensing on sub-flare refrigerators, consisting mainly of sodium chloride and sulfofluoride and refrigeration corrosion products? nickel and copper compounds

The efficiency and feasibility of using fractal methods to study the surface structure of ceramic materials have been investigated. It was found that the fractal formalism can be used as a means of studying the evolution of surface morphology and that multifractal parameters make it possible to judge the degree of homogeneity of the surface structure and the conditions of its formation.

Highly efficient wall ceramics based on expanded perlite, flask and ground glass have been obtained. The possibility of producing solid ceramic bricks (average density 925 kg / m ³ and compressive strength 13.5 MPa) for low-rise construction has been shown

In November 2015, was the 110th anniversary of the birth of Nikolai Mikheevich Pavlushkin? a prominent scientist in the field of chemistry and technology of silicate materials, honored worker of science and technology of the RSFSR, doctor of technical sciences, professor, talented teacher and public figure.

The influence of the parameters of ceramic fabrication on the structure and adhesion of the applied chemical coating has been studied. The relationship between the sintering temperature of ceramic samples and the quality of the subsequent chemical silver coating has been established. It is shown that high-quality coatings are obtained in a narrow temperature range

Are the results of the study of the adhesion layer metal? silicate glass enamel coating on a scanning electron microscope at different magnifications. The influence of the method of metal preparation, methods and modes of coating, the thickness and number of enamel layers on the formation of a layer of adhesion of the glass enamel coating with the steel surface has been assessed.

Provides general information about solid reinforcing materials and steels for rock cutting tools; some problems of efficiency and durability of sintered cermet hard alloys are shown. The possibility of replacing expensive wear-resistant alloys with economically alloyed white cast irons with an increase in mechanical properties, hardness, wear resistance and impact resistance of white cast iron due to the treatment of the melt with nitrogen and an increase in the carbon content is shown. Possible ways of improving the properties of sintered metal-ceramic alloys due to thermal and chemical-thermal treatment are briefly highlighted.

The preparation of a modern highly porous insulating material based on silicon dioxide is shown. Using factor analysis, the most significant parameters influencing the formation of the porous structure of gels obtained from alkoxides by the sol-gel method were determined.
