Abstract
Abstract Microwave dielectric ceramics with the composition of MgZr 1+ x Nb 2 O 8+2 x were prepared by a solid-state reaction route. XRD patterns revealed that the samples consist of monoclinic MgZrNb 2 O 8 and ZrO 2 , and the content of ZrO 2 phase increased with increasing x values. The microwave dielectric properties of samples, such as dielectric constant, Q × f value and temperature coefficient of resonant frequency have been investigated as a function of composition. It showed that the dielectric properties can be improved with the increase of x values. When x =0.32, the temperature coefficient of resonant frequency of MgZr 1+ x Nb 2 O 8+2 x ceramic can be adjusted to a near-zero value of 1.4 ppm/°C, the dielectric constant and Q × f values are 28.03 and 68,600 GHz, respectively. These results indicate that MgZr 1.32 Nb 2 O 8.64 ceramic can be a suitable candidate in microwave dielectric components.
