The aim of this review article on recent developments of mechanochemistry (nowadays
established as a part of chemistry) is to provide a comprehensive overview of advances …

Abstract Calcium copper titanate, CaCu 3 Ti 4 O 12,(CCTO), a potential electro-ceramic is a
member of a very important perovskite family and has been found to a show dielectric …

We present a simple strategy to achieve excellent dielectric and nonlinear current–voltage
properties for pure–CaCu 3 Ti 4 O 12 ceramics prepared by a modified sol–gel method with …

In this work, a sol-gel method was used to synthesize nanometer-sized rutile (La+ Nb) co-
doped TiO 2 powders, which were employed to prepare (La+ Nb) co-doped TiO 2 ceramics …

AC electrical measurements were carried out on iodine doped, CaCu 3 Ti 4 O 12-x I x (x= 0,
0.005, 0.05 and 0.2) ceramic specimens sintered at 1100° C for 12 h in the temperature (300 …

Significantly improved dielectric properties of CaCu 3 Ti 4 O 12 ceramics were
accomplished by co-do** with Y 3+ and Mg 2+ to simultaneously control the geometric …

Different do** elements have been used to reduce the dielectric losses of CaCu 3 Ti 4 O
12 ceramics, but their dielectric constants usually are undesirably decreased. This work …

Abstract The CaCu 3 Ti 4 O 12 ceramic, CCTO, remains as the best material due to its high
dielectric constant. In this context, Sr-doped CCTO, Ni-doped CCTO and Sr, Ni co-doped …

We present a Ti O 2-rich Ca Cu 3 Ti 4 O 12 polycrystalline ceramic with high dielectric and
nonlinear electrical properties. Analysis of the ceramic microstructure and composition …

We report on high dielectric constant (8.3× 10 3, 10 4 Hz), low dielectric loss (0.029, 10 4 Hz)
as well as fine grain size (∼ 840 nm) achieved in pure CaCu 3 Ti 4 O 12 (CCTO) ceramics …
