Inorganic Materials Aims and scope

Abstract—

Using powders synthesized under optimal conditions, we have prepared Li2Zn3Ti4O12 + ZnTiO3 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 Li2O–B2O3–SiO2 system in an amount of 3.0 wt %. The material thus prepared has a high level of dielectric properties: εr = 23.1 and Qf = 832 at a field frequency of 1 MHz.
