Densification and characterization of SiO2B2O3CaOMgO glass/Al2O3 composites for LTCC application
چکیده انگلیسی

A glass/ceramic composite using lead-free low melting glass (SiO2B2O3CaOMgO glass) with Al2O3 fillers was investigated. X-ray diffraction analysis revealed that the anorthite and cordierite phase appeared in the sintered composites. The dilatometric analysis showed that the onset of shrinkage took place at ∼624 °C for all the samples and the onset temperature was independent on the content of glass. The low melting glass significantly promoted densification of the composites and lowered the sintering temperature to ∼875 °C. The addition of 50 wt% glass sintered at 875 °C showed εr of 7.3, tan δ of 1.15×10−3, TEC of 5.41 ppm/°C, thermal conductivity of 3.56 W/m °C, and flexural strength of 184 MPa. The results showed that the SiO2B2O3CaOMgO glass/Al2O3 composites were strong potential candidates for low temperature cofired ceramic substrate applications.
