Abstract
A vacuum insulating panel includes first and second substrates (e.g., glass substrates), a hermetic edge seal, a pump-out port, and spacers sandwiched between at least the two substrates. The gap between the substrates may be at a pressure less than atmospheric pressure to provide insulating properties. The panel may include a getter. The getter may be laser activated in a manner which causes the getter to transform and realize a Ti—Al—V phase (e.g., Al3V0.333Ti0.667) of crystallite material. The getter may be a thin film getter and/or may be elongated in shape.
Claims41
A vacuum insulating panel comprising:
- a first substrate;
- a second substrate;
- a plurality of spacers provided in a gap between at least the first and second substrates, wherein the gap is at pressure less than atmospheric pressure;
- a seal at least partially located between at least the first and second substrates;
- and
- a getter comprising getter material, wherein the getter material comprises a Ti—Al—V crystalline phase of approximately Al3V0.333Ti0.666.
A method of making a vacuum insulating panel, the vacuum insulating panel comprising a first glass substrate, a second glass substrate, a plurality of spacers provided in a gap between at least the first and second glass substrates, a seal provided at least partially between at least the first and second glass substrates, and a getter;
- wherein the method comprises:
- providing the getter in a position exposed to the gap, the getter comprising getter material;
- and
- laser treating and/or activating the getter in a manner causing the getter material to comprise a Ti-AI-V crystalline phase which was not present in the getter material prior to the laser treating and/or activating,
- wherein the Ti-AI-V crystalline phase comprises approximately Al3V0.333Ti0.666.
A method of making a vacuum insulating panel, the vacuum insulating panel comprising a first glass substrate, a second glass substrate, a plurality of spacers provided in a gap between at least the first and second glass substrates, a seal provided at least partially between at least the first and second glass substrates, and a getter;
- wherein the method comprises:
- providing the getter in a position exposed to the gap, the getter comprising getter material;
- and
- laser treating and/or activating the getter in a manner causing the getter material to transform into a getter material comprising a Ti—Al—V crystalline phase of approximately Al3V0.333Ti0.666 that comprises a crystallite size of at least about 10 nm.
