The possibility of spatially selective crystallization of lithium-niobiumgermanateglasses with compositions (molar content, & # 37;) 25Li 2 O & middot; 30Nb 2 O 5 & middot; 45GeO has been demonstrated ...
The possibility of laser crystallization of lithium-niobium silicate glasses by means of nanosecond laser pulses in the visible and UV ranges has been demonstrated. Irradiation of glasses with the composition ...
Methods of laser micro- and nanomodification structure of transparent dielectrics open promising prospects for the creation of a new type glass-crystalline materials and new applications. In this work, ...
We have obtained the X-ray total scattering patterns at wavelength 0.20735 ? and corresponding to them radial distribution functions (RDF) of electron density for glasses in the La2O3–Nb2O5–B2O3 and BaO–Nb2O5–P2O5 ...
The conditions for the formation of microregions with polarization-dependent birefringence in sodium-borate glasses with different Na 2 O contents by a femtosecond laser beam are found. The dependences ...
The possibility of the formation of birefringent microregions in sodium borosilicate glass with the composition 68 SiO 2 , 27 B 2 O 3 , 4 Na is demonstrated. 2 O, 1 Al 2 O 3 (molar content, & ...
The process of phase formation in the BaCO 3 + TiO 2 system has been studied using solid-phase reactions and synthesis from a melt obtained by exposure to concentrated solar radiation of various power. ...
