数の温度安定度が大きすぎたりするという欠点がある。In recent years, especially as the integration technology of microwave circuits has progressed, there has been an active effort to use dielectric ceramics with high dielectric constant, low loss, and low cost to stabilize the frequency of oscillators and to miniaturize them. progress is being made. Conventionally, these dielectric materials include BaO-TiO2-based porcelain, porcelain in which a part of BaO-TiO2 is replaced with other elements, and TiO2, which has a negative dielectric constant that changes with temperature, and TiO2, which has a positive dielectric constant that changes with temperature. In many cases, a combination of dielectric porcelain and porcelain is used. However, these have drawbacks such as large dielectric loss, large variations in temperature change in dielectric constant, or too large temperature stability of resonant frequency.

The starting materials are weighed according to each composition, and mixed with pure water in a ball mill equipped with agate balls and lined with rubber.
Wet mixed. This mixture was taken out from the ball mill, dried, calcined in air at 1200° C. for 5 hours, and then wet-pulverized using a ball mill. After taking out the crushed slurry from the ball mill and drying it, it was molded into a disk with a diameter of 25 mL at a pressure of 700 mm.
Firing was performed in air at a temperature within the range of 60 to 1360°C for 2 hours to obtain porcelain having the composition shown in the table below. Next, a disc-shaped porcelain sample with a diameter of 5Trrfn and a thickness of 2 is cut out from each porcelain, and its resonance frequency (approximately 1
The dielectric constant (ε) was measured from the diameter (1 GHz) and the no-load Q (Q1) by the band reflection method. The temperature stability (τf) of the resonant frequency is determined by placing each sample in a temperature bath and setting it at -30
The trap frequency was determined by measuring the change in trap frequency as the temperature changed from ℃ to +70℃. The results are shown in the table below. however※
