PHASE-SEPARATED GLASS, METHOD FOR PRODUCING PHASE-SEPARATED GLASS AND COMPOSITE SUBSTRATE USING PHASE-SEPARATED GLASS

WIPO Patent Application WO/2015/186584

A1

This method for producing phase-separated glass is characterized in that phase-separated glass which comprises at least a first phase and a second phase is obtained by forming phase-separable glass having a refractive index (nd) of 1.65 or more and subsequently subjecting the obtained phase-separable glass to a heat treatment. This phase-separated glass has a refractive index (nd) of 1.65 or more and a phase-separated structure comprising at least a first phase and a second phase, and may have a difference of 40% or less between the maximum value and the minimum value of the total light transmittance at a wavelength of 400-700 nm. In addition, this phase-separated glass has a refractive index (nd) of 1.65 or more and a phase-separated structure comprising at least a first phase and a second phase, and may be configured such that the SiO2 content in the first phase is higher than the SiO2 content in the second phase.
