Abstract

PURPOSE: To produce the title glass for a milk white coating, which can be baked at a low temp., by melting glass having a compsn. most of which except water consists of specified metal oxides; quenching the melt; and recalcining the resulting frit.
CONSTITUTION: Glass is melted having a compsn. above 99 wt% of which except water consists of, by wt., SiO2 4.5W34.0%, B2O3 13.5W40.0%, Al2O3 17.0W 42.0%, RIIO+R2IO 15.0W40.0%, SnO2+TiO2+ZrO2 2.0W15.0%, SnO2 0W 15.0%, TiO2 0W15.0% and ZrO2 0W15.0%. The melt is quenched by charging in water or other method, and the resulting almost transparent frit is recalcined at 600W750°C to obtain milk white low m.p. crystallized glass. In the above formulae RII is one or more out of Mg, Ca, Ba, Sr and Zn, and RI is one or more out of Li, Na, and K.
