چکیده مقاله
Calcium titanate CaTiO₃ Perovskite has been used in various industrial applications due to dopant/doping mechanisms Manipulation of defective grain boundaries in structure of perovskite is essential to maximize mechanical properties and stability, therefore attention to the structure of perovskite is done, because without mastering on the perovskite structure and diffracted planes, dopant/doping mechanisms are not understandable In this study, area and locations of atoms and diffracted planes were designed and investigated In this research, relationship between Young's modulus and planar density of unit cell, super cells 2×2×2 and symmetry cells of nano CaTiO₃ is investigated In this case, elastic constant, elastic compliance and Young's modulus value were recorded through the ultrasonic pulse echo technique As the result, C11=330 89 GPa, C12=93 03 GPa, C44=94 91 GPa and E=153 87 GPa tandemly Young's modulus values of CaTiO₃ extracted by planar density were calculated 162 62 GPa, 151 71 GPa and 152 21 GPa for unit cell, super cells 2×2×2 , and symmetry cells respectively Young's modulus value extracted by planar density of symmetry cells was in the well agreement with Young's modulus value measured via ultrasonic pulse echo
