摘要: A sealing glass composition in powdered form comprising a crystallizable PbO/ZnO/B2O3/SiO2 glass in the vitreous state, an effective amount of a nucleating agent, and an optional filler. The glass composition can be used to seal television picture tubes with excellent results when heated to a hold range of about 420° C. to about 435° C.
