Dielectric materials based on titanium, tin and zirconium oxides, corresponding to the following composition: t TiO2, s SnO2, z ZrO2 t, s and z denoting the molar coefficients and satisfying the following relationships: s + z + t = 2 0.75 </= t </= 0.9 0.225 </= s </= 0.3 0.8 </= z </= 0.975 These materials may be advantageously employed to produce dielectric resonators for ultrahigh-frequency oscillators with high stability to temperature. |
