Influence of B2O3 content on sintering behaviour and dielectric properties of La2O3-B2O3-CaO/Al2O3 glass-ceramic composites for LTCC applications

摘要：

　　La2O3-B2O3-CaO glasses with different B2O3 content were synthesized by melting method to produce glass/ceramic composites in this work.XRD and DSC results revealed that the diminution of B2O3 content was beneficial to increase the crystallization tendency of glass and improve the quality of crystalline phase,while decreasing the effect of glass during sintering process as sintering aids.The choice of glass/ceramic mass ratio was also influenced by the B2O3 content of glass.Dense samples sintered at 875 oC showed good dielectric properties which meet the requirement of LTCC applications: moderate dielectric constant(7.8-9.4)and low dielectric loss(2.0×10-3).
