Matching correlation study of titanium-based ceramics with glass based on dissolution characteristics

Glass-ceramics are ideal candidates in Low-temperature Cofired Ceramic (LTCC) technology. The “dissolution-precipitation” mechanism ensures the sintering compactness of glass-ceramics at low temperatures. The ceramics must be dissolved and precipitated in the liquid phase with the assistance of glass additives. In this case, the characterization of dissolution behaviors that should be highly valued has rarely been emphasized. This study puts forward a simple, repeatable, and efficient design for characterizing the dissolution behaviors of several titanium-based ceramics in glass frits under variable temperature conditions. Interestingly, a glass frit with good wettability does not ensure the low-temperature sintering process of a ceramic matrix. In contrast, the dissolution characteristics of ceramics in the glass should be seriously considered. Hopefully, the study of dissolution behaviors could strengthen the fundamental understanding of the low-temperature sintering of ceramics and offer a glass-ceramic design strategy for developing high-performance.
