Effect of Sr2+ substitution on structural, morphological, electrical and dielectric properties of Ca2MgSi2O7 ceramic
Despite the excellent properties of ceramic materials for electronic devices, this study systematically investigates the significant effects of strontium (Sr2?) substitution on the structural, morphological, electrical, and dielectric behavior of Ca2-xSrxMgSi2O7 (x = 0, 0.2, 0.4, 0.6) ceramics.
