High-energy ball milling as a green chemistry method for modification of CaTiO3 electrical properties
Elec. properties of CaTiO3 were modified with Cu ions by high-energy ball milling in air. Several solid state solns. of Ca1-xCuxTiO3 (0 <= x <= 0.8) and CaTi1-xCuxO3-delta (x = 0.02 and 0.20) were produced. The addn. of Cu resulted in an improvement of dielec. permittivity, dielec. loss and conductivity of the solns. The optimum compn. was CaTi0.80Cu0.20O3.
