摘要： 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 vacuum insulating panel may include at least one passivation layer for reducing outgassing from a glass substrate, in order to improve lifespan of the vacuum insulating panel.

摘要： 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, and a seal provided between at least the first and second glass substrates, the seal comprising a first seal layer and/or a second seal layer. The method may include laser heating, using a laser beam from a continuous wave near-IR laser, seal material in order to form the first seal layer; wherein the laser heating may include causing the laser beam to move at a lateral speed of from about 5-70 mm/second relative to the substrates and the first seal material so that the laser beam at least partially passes through at least one of the glass substrates and impinges upon at least the second seal layer in order to heat the second seal layer and fire and/or sinter the first seal material thereby forming the first seal layer.

摘要： A vacuum insulating panel may include: 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 pump-out/evacuation tube extending at least partly into an aperture in one of the substrates; and a pump-out/evacuation tube seal. The pump-out/evacuation tube seal may include at least one of: (a) from about 20-80 wt. % tellurium oxide, the tellurium oxide comprising TeO4 and TeO3, wherein the pump-out tube seal comprises more TeO3 than TeO4 by wt. %; and/or (b) tellurium oxide and from about 10-50 wt. % vanadium oxide, wherein the pump-out tube seal by wt. % comprises more tellurium oxide than vanadium oxide, and wherein the vanadium oxide comprises VO2 and V2O5, and wherein more V in the pump-out tube seal is in a form of VO2 than V2O5. A substantially donut-shaped laser beam may be used to heat pump-out tube material in order to form a pump-out tube seal.
