Preparation and Properties of Li2Zn3Ti4O12-Based Ceramics with a Sintering Aid in the Li2O–B2O3–SiO2 System for LTCC Technology

— Using powders synthesized under optimal conditions, we have prepared Li 2 Zn 3 Ti 4 O 12 + ZnTiO 3 ceramics suitable for designing microelectronic components by low-temperature cofired ceramic (LTCC) technology. The sintering temperature of the ceramics has been lowered from 1075 to 950°C by addin...

Zusammenfassung:— Using powders synthesized under optimal conditions, we have prepared Li 2 Zn 3 Ti 4 O 12 + ZnTiO 3 ceramics suitable for designing microelectronic components by low-temperature cofired ceramic (LTCC) technology. The sintering temperature of the ceramics has been lowered from 1075 to 950°C by adding a sintering aid with a eutectic composition in the Li 2 O–B 2 O 3 –SiO 2 system in an amount of 3.0 wt %. The material thus prepared has a high level of dielectric properties: ε r = 23.1 and Qf = 832 at a field frequency of 1 MHz.
