The microwave dielectric properties of Ca(Li1/3Nb2/3)O3-delta sintered at 1150degreesC exhibit a the dielectric constant (epsilon(r)) of 29.6, a Q(.)f(0) of 40000 GHz, and a temperature coefficient of resonant frequency (tau(f)) of -21 ppm/degreesC. To control of the tau(f) of Ca(Li1/3Nb2/3)O3-delta, Zr4+ was substituted for [Li1/3Nb2/3](3.67+). As the Zr content increased, the epsilon(r) slightly increased and the tau(f) shifted to positive and then negative value. However, the Q(.)fo initially increased and then continuously decreased. A new composition having high Q(.)f(0) (approximate to36300 GHz), high epsilon(r) (approximate to30), stable tau(f) (approximate to -5 ppm/degreesC), and relatively low sintering temperature (1150degreesC) was developed and the relationship between microstructure and microwave dielectric characteristics was investigated.
