Investigation of the Mixing Medium Effect on the Development of the CCTO Microstructure at 1000 ̊C

In this work, CCTO ceramics with high permittivity were synthesize using solid state reaction. The raw materials such as CuO, CaO and TiO2 were prepared in dry medium and wet medium (deionized water, distilled water and ethanol) and calcined at 1000oC for 5 h. From this study, mixing medium effect on CCTO microstructure and it can control the growth of CCTO. This part is significant for the progress of CCTO. Particle size of CCTO prepared using dry medium is homogenous and largest compare to CCTO prepared using wet medium. This is relate to conversion rate and the existence of pore inside CaO and empty space between particles
