A glass composition for a tubular glass body used to form a glass-metal joint in a tubular solar collector. Includes a borosilicate glass having a dilatometric chart with a hard segment and a soft- segment hysteresis. The soft segment glass transition temperature is less than the hard-segment glass transition temperature for a temperature difference ΔT higher than 20° C. The composition comprises: 5% to 8% Na 2 O, O, 1% to 3% K 2 0, O, 1% to 1.5% CaO, 5% to 7.5% Al 2 0 3 , 70% to 75% Si0 2 , 11.6% to 13.7% B 2 0 3 , Owing and owing to the choice of the B 2 0 3 in the range indicated, in combination with the other components, there is a glass transition temperature lower than other borosilicate glasses. The remarkable difference between the soft and hard segments glass transition temperatures make it possible to obtain a tubular glass body particularly suitable for a solar collector.

An antimony-free glass comprising TeO 2 and/or Bi 2 O 3 suitable for use in a frit for producing a hermetically sealed glass package is described. The hermetically sealed glass package, such as an OLED display device, is manufactured by providing a first glass substrate plate and a second glass substrate plate and depositing the antimony-free frit onto the first substrate plate. OLEDs may be deposited on the second glass substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first glass substrate plate to the second glass substrate plate and also protects the OLEDs disposed therein. The antimony-free glass has excellent aqueous durability, good flow, and low glass transition temperature.

An antimony-free glass suitable for use in a frit for producing a hermetically sealed glass package is described. The hermetically sealed glass package, such as an OLED display device, is manufactured by providing a first glass substrate plate and a second glass substrate plate and depositing the antimony-free frit onto the first substrate plate. OLEDs may be deposited on the second glass substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first glass substrate plate to the second glass substrate plate and also protects the OLEDs. The antimony-free glass has excellent aqueous durability, good flow, low glass transition temperature and low coefficient of thermal expansion.
