Abstract

The microstructures and the microwave dielectric properties of the (1-x) (Mg_0.9Zn_0.1)TiO_3-x (Ca_0.61La_0.26)TiO₃ (MZCLT hereafter) ceramic system were investigated. The objective of the present work is to compensate for the negative temperature coefficient of resonant frequency of (Mg_0.9Zn_0.1)TiO₃ by the addition of (Ca_0.61La_0.26)TiO₃. MZCLT ceramics exhibited mixed phases of (Mg_0.9Zn_0.1)TiO₃ and Ca_0.61La_0.26TiO₃ as the main phases associated with minor phase of (Mg_0.9Zn_0.1)Ti₂O₅. With increasing x, the dielectric constant increased and the quality factor Q·f decreased. For x=0.15, the MZCLT exhabites excellent microwave dielectric properties: ε_r=25.59, Q·f=96000 GHz and τ_f=+1×10^-6/°C at 1325°C.
