Abstract

PURPOSE: To provide the title low m.p. glass compsn. esp. suitable for sealing the panel and funnel of a color TV cathode-ray tube which compsn. consists of low m.p. crystalline glass powder finishing sealing in a crystallization state through low temp. heat treatment and of low expansion refractory filler powder.
CONSTITUTION: A sealing compsn. is provided consisting of PbO-B2O3-ZnO-SiO2 type low m.p. crystalline glass powder of a specified compsn. and a predetermined ratio of low expansion ceramic filler powder. This compsn. consists of low m.p. crystalline glass powder composed of, by wt., PbO 77.0W83.0%, B2O3 7.0W11.0%, ZnO 7.0W12.0% and SiO2 1.0W3.0%, and of one or more kinds of low expansion refractory filler powder such as cordierite 2.0W15% and β-eucryptite 2.0W15%. This compsn. can be used in a crystallization state in the above-mentioned sealing by heat treatment at below 420°C.
