Analysis of Phase Change of BaTiO3 Ferroelectric Material from a Tetragonal Crystal Structure (BaTiO3) to Orthorhombic (Ba4Ti13O30) to Monoclinic (Ba6Ti17O40)

Abstract

Abstract BaTiO3 ferroelectric material is very interesting to study, because BaTiO3 ferroelectric material has spontaneous polarization properties when given an electric field from outside the system. This spontaneous polarization property of BaTiO3 ferroelectric material can be applied as a light sensor (ferroelectric properties), temperature sensors (pyroelectric properties), pressure sensors (piezoelectric properties). Has successfully analyzed the phase change of BaTiO3 ferroelectric material from a tetragonal crystal structure (BaTiO3) to orthorhombic (Ba4Ti13O30) to monoclinic (Ba6Ti17O40) using the Cramer-Cohen method. This shows that the Cramer-Cohen method is very accurate in calculating the lattice constants of the crystal structure of ferroelectric materials and other materials.
