Sealants, vacuum insulated glazing (VIG) units having seals formed from the sealants, and methods for producing the VIG units using the sealants are provided. The sealants include a mixture of glass materials in powder form, a foaming agent in powder form, and a carrier medium. The foaming agent includes carbon black, carbide(s), or a combination thereof. The glass materials have compositions including: 50 to 70 wt. % SiO; 1 to 7 wt. % CaO; 0 to 7 wt. % MgO; 0 to 6 wt. % AlO; 1 to 6 wt. % FeOor FeO; 0 to 7 wt. % TiO; 0 to 16 wt. % RO, wherein R is chosen from the group consisting of Li, Na, K, or a combination thereof; 0 to 1 wt. % SO; 0 to 2 wt. % MnO; and 0 to 6 wt. % SrO+BaO.

Methods, vacuum insulated glazing units produced thereby, and sealants

Methods and vacuum insulated glazing units are provided. The methods include providing a first pane, applying a primary sealant to the first pane adjacent to and along a perimeter of the first pane, positioning support pillars on the first pane, positioning an evacuation tube on the first pane, positioning a second pane on the support pillars, heating the primary sealant with a laser beam sufficient to sinter the primary sealant to form a primary seal joining the first and second pane, evacuating an intermediate space defined between the first and second pane, and the primary seal to produce a low-pressure environment in the intermediate space by drawing gas from the intermediate space through the evacuation tube, and sealing the evacuation tube and thereby hermetically sealing the intermediate space within the first and second pane, the primary seal, and the evacuation tube to maintain the low-pressure environment therein.
