La2O3/Al2O3/B2O3 Based Glass-Ceramics for LTCC Application

Article Preview

Abstract:

La2O3-Al2O3-B2O3 (LAB) glass with Al2O3 particulates is a lead-free, non-alkali, and low-sintering temperature glass-ceramic system, which has been developed for LTCC application. The glass melting and sintering process window of the LAB systems were investigated. A systematic study on the wetting behaviors of the LAB glass on alumina plate, microstructures and crystallization in the glass-ceramics had also been conducted. The densification and crystallization temperatures of the glass-ceramics took place as low as 800oC. The interface condition of layer glass-ceramics with Ag electrode was also characterized. No obvious interfacial diffusions were observed.
