Phase composition of lithium aluminosilicate glass-ceramics

The phase composition of glass-ceramics produced by heat-treating lithium aluminosilicate glass at temperatures from 600 to 1300 deg C has been determined by x-ray diffraction and electron probe x-ray microanalysis. The materials heat-treated in the range 1000-1230 deg C have been shown to contain a...

Description
Summary:The phase composition of glass-ceramics produced by heat-treating lithium aluminosilicate glass at temperatures from 600 to 1300 deg C has been determined by x-ray diffraction and electron probe x-ray microanalysis. The materials heat-treated in the range 1000-1230 deg C have been shown to contain an SiO.65Al0.19Ti0.09Sb0.013Na0.032K0.013Ce0.008As0.013O1.864 glass phase and crystalline solid solutions: tetragonal spodumene-like Li1 - 4x - 2y TixZnyAlSi3O8 (x, y 1.92Ti0.08SiO5.04, and rutile-based Ti0.99Sb0.01O2.005. The structures and lattice parameters of the crystalline phases have been determined.
