DIELECTRIC COMPOUND FOR CONTRAST COATING ON GLASS SUBSTRATE UNDER LOW-MELTING GLASS Russian patent published in 2002 - IPC

FIELD: electronic engineering; DC and AC gas panel manufacture. SUBSTANCE: black-color contrast coating is produced on glass substrate under low-melting glass possessing mechanical and chemical stability to low-melting glass when exposed to temperatures higher than melting point of low-melting glass by using dielectric compound incorporating glass with deformation temperature t_d1 equal to 0,9 T_d.gl.sub≥t_d1≥1,08 T_d.l.m.g in the amount of 35-45% and low-melting black-color component in the amount of 55-65%, where T_d.l.m.g is deformation temperature of low-melting glass; T_d.gl.sub is glass substrate deformation temperature. EFFECT: enhanced mechanical and chemical stability of coating when exposed to temperatures higher than melting point of low-melting glass. 1 tbl
