Abstract
"New compositions of low-temperature black enamels have been developed. Compositional modifications were made to the ZnO-Fe2O3-P2O5 (ZFP) and ZnO-V2O5 - P2O5 (ZVP) systems studied previously at UMR to obtain the desired glass properties, including coefficient of thermal expansion (CTE) in the range 8-10 x 10-6/⁰C , corrosion resistance in HCl and DI water comparable to that of soda-lime window glass, low glass transition temperatures (Tg) ~< 450⁰, low sealing temperatures (< 700 °C) and the wetting of the enamel to window glass substrates. Substitutions of MnO, CuO, Li2O, NiO, La2O3, Na2O and K2O for ZnO were made to alter the properties of the base glasses to achieve a particular range of Tg, CTE and chemical durability and to alter the glass color. ZVP glasses with ZnO (up to 20 mol %), V2O5 (5-10 mol %), and P2O5 (40-50 mol %) and ZFP glasses with ZnO (up to 20 mol %), Fe2O3 (10-20 mol %), and P2O5 (40- 50 mol %) proved to have the best combination of thermal and chemical properties. Glasses modified with Na2O and K2O have the desired range of thermal properties and durability and the addition of MnO proved to have a positive impact on the acid resistance of the enamel. These glasses possess weight loss rates < 10-6g/cm2 .min in 80°C deionized water and HCl (pH-3). Scanning electron microscopic (SEM) analyses of enamels bonded to window glass show good wetting characteristics at 650°C"--Abstract, page iii.
