Structural inhomogeneity in glasses from the system Li2O3–Al2O3–SiO2 revealed by IR spectroscopy

摘要: Abstract MIR spectra of lithium silicates and aluminosilicates were measured compared with the simulated spectra. Simulation was carried out by mathematical summation appropriate glass taken in right proportion. It shown that obtained this way are very similar to confirms phase inhomogeneity studied glasses short or even medium range order. Structures silicate aluminosilicate consist structural elements resulting from its composition position field primary crystallisation. The structure these is their crystalline analogues same chemical composition, but they much more disordered do not have translation symmetry.
