摘      要：The effects of the Ca0.7Nd0.2Ti O3 ceramic addition on the crystallization,densification,and dielectric properties of CaO–B2O3–SiO2–(Al2O3)glass(C1:CaO–B2O3–SiO2 glass and C1A03:CaO–B2O3–SiO2–Al2O3 glass)for low-temperature co-fired ceramic(LTCC)applications are *** cristobalite phase crystallized from C1 glass was inhibited by adding *** sintering,Ca0.7Nd0.2TiO3 ceramic reacted with CaO–B2O3–SiO2–(Al2O3)glass to form the sphene(CaTiSiO5)*** amount of sphene phase increases with increasing sintering *** adding 50–60 wt%C1 or C1A03 glass,Ca0.7Nd0.2TiO3 can be densified at 850–900℃.The relative dielectric constants for Ca0.7Nd0.2TiO3 added with C1 and C1A03 glasses were all 20–***0.7Nd0.2TiO3 added with C1 glass exhibited a lower dielectric constant than C1A03 glass due to cristobalite phase *** Ca0.7Nd0.2TiO3 ceramics added with 50 wt%glass,the variation in Q×f value presented the same trend as the sphene formation amount *** best Q×f value of 2380 GHz was achieved for Ca0.7Nd0.2TiO3 ceramics added with 50 wt%C1A03 glass sintered at 900℃due to the dense structure and greater amount of ***0.7Nd0.2TiO3 ceramics added with50 wt%C1A03 glass sintered at 900℃exhibited a dielectric constant of 22.8 and Q×f value of2380 GHz,which are suitable for microwave LTCC applications.
