Abstract
A microwave (MW) treatment process was performed to pre-sintered of CaCu3Ti4O12. Conventional furnace was used for calcinationd and sintered process, whereas a domestic microwave oven employed for treatment in order to produce the better phase structures, morphology and dielectric properties of CaCu3Ti4O12 products. Analysis SEM show that the microstructures of MW treated sample is better densification, fine and larger grain size if compare to the untreated sample. Dielectric properties also have been improved by MW treatment, which is higher dielectric constant and lower dielectric loss. The effect of doping concentration of SnO2 to dielectric properties of CaCu3Ti4O12 had been studied. It was found that the dielectric constant of CaCu3Ti4O12 decreased exponentially with molarities percentage of SnO2. The lowest dielectric loss value has been obtained at sample with 6 mol% doping concentration.
