An overview of the dielectric properties of ceramic materials based on solid solutions of alkali-earth metal titanates with a perovskite structure is presented. The ranges of solubility of the components of two- and three-phase solid solutions are determined and the influence of the component concentration ratios, production methods and technological parameters on the dielectric properties of ceramics is shown. Based on the literature data, a three-component phase diagram for BaTiO3, CaTiO3, and SrTiO3 was compiled for the first time, which shows the relative permittivity values characteristic of various regions in the phase diagram. It was found that ceramics with a content of Ba2+ > 40 mol. %, Sr2+ < 60 mol. % and Ca2+ < 40 mol. % have the highest values of relative permittivity (>700), and an increase in the proportion of Sr2+ and Ca2+ leads to its significant decrease.
