The effect of the eutectic additive of the system Li2O–B2O3 on the sintering process and the dielectric properties of Li2MgTi3O8-based ceramics was studied. It was found that the introduction of an additive in amounts 10.0 – 15.0% promotes sintering of ceramics by means of a liquid-phase mechanism. Li2MgTi3O8-based ceramic, containing a sintering additive in the amount 15.0% and fired at 900°C, demonstrates the following property levels: average density ρav = 3.04 g/cm3, open porosity Po = 5.7%, relative dielectric constant εr = 19.0, and dielectric loss tangent tan δ = 0.028. The lowered sintering temperature of the ceramic will allow the manufacture of different electronic components based on it, using low-temperature co-firing ceramic (LTCC) technology, and the a specified level of dielectric properties will allow the miniaturization of devices.
