Summary

The role of fluorine in titania-opacified cover coat enamels is examined from a glass structure standpoint. Experimental data show that the incorporation of fluorine into titania-opacified enamel glasses enhances the crystallization of titania, affects the reflectance and color, increases the coefficient of thermal expansion, and degrades the chemical durability of the enamel glasses.
