Abstract
Lead and bismuth glass systems have different wettability, which affects the mixture of the paste (vehicle and frits) and the burn-out of the vehicle within a thick film. This study examined the reaction between the vehicle (ethyl cellulose (EC) with α-terpineol) and oxide glasses (PbO and Bi2O3 glasses). The contact angle with the vehicle on the Bi2O3 glass was found to be higher than that on the PbO glass. This suggests that Bi2O3 glass has lower driving force and work of adhesion than PbO glass.
