Heading: Science for ceramic production

The process of phase formation in the BaCO 3 + TiO 2 system has been studied using solid-phase reactions and synthesis from a melt obtained by exposure to concentrated solar radiation of various power. It is shown that in the power range up to 100 W / cm2, barium metatitanate BaTiO 3 of the cubic system is formed; with an increase in the radiation power, a tetragonal phase of barium titanate is formed. The obtained barium titanates have high values ??of dielectric constant (3000? 3200) and low dielectric losses.
