Laminated glass articles with phase-separated claddings and methods for forming the same

摘要

Laminated glass articles and methods for making the same are disclosed. In one embodiment, a laminated glass article may include a glass core layer and at least one glass cladding layer fused to the glass core layer. The at least one glass cladding layer may be phase separated into a first phase and at least one second phase having different compositions. The first phase of the at least one glass cladding layer may have an interconnected matrix. The at least one second phase of the at least one glass cladding layer may be dispersed throughout the interconnected matrix of the first phase of the at least one glass cladding layer. In some embodiments, the at least one second phase may be selectively removed from the interconnected matrix leaving a porous, interconnected matrix of the first phase.
