• Cudoped ZnO (Zn 1x Cu x O) nanoceramics were prepared by ballmilling of the CuO and ZnO powders. • Up to 3 at% of Cu could be doped in ZnO via ball milling, beyond which Cu precipitates as CuO during calcination. • The ac conductivity values decrease by Cu doping in ZnO, making it a better dielectric material.
research has been focused either on the effect of CuO and ZnO on the clinkering process and their incorporation in the clinker phases or on the retarding effect of Zn and Cu compounds added directly in cement. This paper concerns the addition of wt.% ZnO and CuO in a Portland cement raw meal and their effect on cement hydration and properties.
In view of leadfree lowsoftening CuO–ZnO–B 2 O 3 –Li 2 O glass, novel glass/Al 2 O 3 ceramic composites were prepared by solidstate reaction route for ultralow temperature cofired ceramic (ULTCC) applications. The phase evolution and compositions, microstructure and microwave dielectric properties of the composites were studied by XRD, SEM and dielectric property measurement.
