摘要

1. Glass-solder material containing a composition that contains bismuth oxide, zinc oxide, boron oxide, aluminum oxide and magnesium oxide in sufficient quantities to absorb at least 80% of the energy of incident infrared radiation having a wavelength of from 1100 to 2100 nm. 2. A glass solder material containing a composition that contains bismuth oxide, zinc oxide, boron oxide, alumina, and magnesium oxide, wherein the glass solder material is substantially melted when the glass solder material is held at a temperature of not more than 525 ° C. for no more than about 3 minutes. 3. Glass-solder material according to claim 2, wherein the temperature is not more than 485 ° C. 4. A method of manufacturing a sealing around the perimeter of a vacuum glass unit, comprising: exposure to infrared radiation energy from at least one infrared radiation source operating at a first voltage for a first predetermined period of time on glass-solder material; reducing the operating voltage of at least one source infrared radiation from the first voltage to the second voltage for a second predetermined period of time, so as to reduce the energy of infrared radiation incident on the glass-solder material; increasing the operating voltage of at least one infrared radiation source from the second voltage to the third voltage during the third predetermined period of time, so as to increase the energy of infrared radiation incident on the glass-solder material; forced or spontaneous
