Improvement in dielectric and mechanical performance of CaCu 3.1Ti 4O 12.1 by addition of AL 2O 3 nanoparticles
The properties of CaCu3.1Ti4O12.1[CC3.1TO] ceramics with the addition of Al2O3nanoparticles, prepared via a solid-state reaction technique, were investigated. The nanoparticle additive was found to inhibit grain growth with the average grain size decreasing from approximately 7.5 μm for CC3.1TO to a...
