Temperature Compensated (1-x)(Na0.5La0.5)TiO3+xCeO2 Microwave Dielectric Ceramics Incorporated with Copper Oxide
The microstructures and microwave dielectric properties of temperature compensated composite ceramics (1-x)(Na0.5La0.5)TiO3+xCeO2 doped with 1wt%CuO were investigated. Dense and mixed phase samples were produced in the range of 0.1 ≤ x ≤ 0.9. As x value increases the Qf increases nonlinearly while the dielectric constant decreases almost linearly. The compensated τf value is obtained in 0.1(Na0.5La0.5)TiO3 + 0.9CeO2 + 1wt%CuO ceramic with the Qf and εr being 8240GHz and 32.0 respectively.
