Low-Temperature Preparation of the BaO-B₂O₃ Matrix Composite Ceramics

Abstract

In this work, the energy-saving LTCC composite ceramics containing quartz, fused quartz and zirconia ceramic particles, respectively based on the binary system BaO-B2O3 were prepared by traditional solid-state preparation process at a sintering temperature of 900°C. Sintering mechanism and physical properties of the LTCC composite ceramics are investigated and discussed in detail in terms of their mineral phase composition. The results indicate that the introduction of α-alumina to the binary system BaO-B2O3 can improve the sintering behavior whereas the presence of the functional ceramic particles in the composite ceramics is important to achieve the peculiar physical characterlistics, which consequently supply more possibilities to regulate on the physical properties of the composite ceramics.
