Abstract
A glass-ceramic includes glass and crystalline phases, where the crystalline phase includes non-stoichiometric suboxides of titanium, forming ‘bronze’-type solid state defect structures in which vacancies are occupied with dopant cations.
Claims20
A glass-ceramic article, comprising:
- a bulk comprising an amorphous phase and a crystalline phase, wherein the crystalline phase comprises a plurality of precipitates homogenously distributed within the amorphous phase, wherein the precipitates comprise a bronze-structure;
- and
- a bleached region having a localized composition that differs from the bulk due to dissolution of the precipitates.
A glass-ceramic article, comprising:
- a bulk comprising an amorphous phase and a crystalline phase, wherein the crystalline phase comprises a plurality of precipitates homogenously distributed within the amorphous phase, wherein the precipitates comprise a tungsten-bronze structure;
- and
- a bleached region that differs from the bulk due to absence of the precipitates.
A glass-ceramic article, comprising:
- a bulk comprising an amorphous phase and a crystalline phase, wherein the crystalline phase comprises a plurality of precipitates, wherein the precipitates comprise a bronze structure;
- and
- a bleached region,
- wherein the bulk is opaque in the visible spectrum 400-700 nm, and
- wherein the bleached region has transmittance of 5%/mm or greater over at least one 50 nm-wide wavelength band of light in the visible spectrum 400-700 nm.
