摘要：

With the wide application of multi-layer ceramic capacitors (MLCC), low-melting borosilicate glasses for copper pastes are highly desired. Herein, Zinc borosilicate manganese glasses with the molar composition of (60-x) ZnO-30B(2)O(3)-10SiO(2-x)MnO(2) (ZBSM), (x between 0.0 +/- 20.0 mol%) were designed for MLCC copper paste. The copper terminal paste sintering temperature can reduce to 780 degrees C by increasing the content of MnO2 in ZBSM glass from 0 to 20% mol ratio. The DSC results show the glass transition temperature decreases with the increase of MnO2 content. The entry of Mn4+ as a network modifier to change the network structure. Notably, the ZBSM glass based on copper paste demonstrated remarkable acid tolerance, excellent conductivity of 2.05 m; and long-term stability, exhibiting great promise for application in the MLCC industry.
