摘要：

In this study, the performance of low-temperature sintered Bi-B-Si-Zn-Al glass/Al2O3/SiC nanowires composite fabricated by the tape casting method was systematically investigated. The thermal conductivity of the composite sintered at 900 degrees C for 2 h increased from 4.356 W/(mK) to 6.868 W/(mK) by incorporating 0.5 wt% SiC nanowires, and the dielectric constant and the dielectric loss angle tangent were 4.21 and 1.10 x 10-2 at 25 GHz, respectively. The sintered sheet containing 0.5 wt% SiC nanowires had a low thermal expansion of 4.53 ppm/degrees C at 25 degrees C-200 degrees C. Microstructure and XRD analysis indicated the formation of ZnAl2O4 crystal. The network model was introduced to analyze the enhancement of thermal conductivity when adding 1.25 wt% SiC nano -wires. Such low-temperature co-fired ceramic (LTCC) may have a promising application in the field of electronic substrate.
