When comparing the optical characteristics of the obtained glasses in the UV region of the spectrum, it was shown that the glasses welded from KFK have greater transparency and higher transmission in the ...
This paper presents the results of annealing synthetic quartz glass of high purity at a temperature of 250 ?C and an elevated pressure of 7 MPa in an atmosphere of molecular hydrogen. Annealing under these ...
Ceramics in the CaO–SiO2 and Na2O–CaO–SiO2 systems were obtained from powders synthesized from aqueous solutions of silicic acid and calcium nitrate at a molar ratio of Ca/Si = 0.5 by direct precipitation ...
The article provides an overview of mineral oxide fibers of various chemical composition: aluminosilicate, alumina, silica, bio-soluble, zirconium oxide fibers and others. Methods for producing discrete ...
A sequence of operations for the manufacture of quartz glass samples from natural highly enriched raw materials and syntheticsilicondioxide is described and implemented. The main attention is paid to ...
