Abstract

Dielectric materials based on the BaTiO3 and MgTiO3 with different dopants substituting Ba and Mg have been investigated. The influence of small additions on the microwave characteristic has been studied. The dielectric properties of the examined materials with partially replaced metal atoms (Ba or Mg) or Ti atoms has been determined. The influence of substitutes has been discussed in terms of discovering new material with optimal dielectric characteristics..
