| Summary: | 碩士 === 國立交通大學 === 材料科學與工程系 === 87 === There are two part of discussions were included in this study. The first part we cover the PbO on the La4Ti9O24 substract , by changing the holding temperature and time, discussing the diffusion mechanism and the thickness change of reaction layer.
The second part is adding PbO on La4Ti9O24 to synthesize (Pbx,La1-x)2/3TiO2.993. By controling the composition of PbO-La4Ti9O24 and the sintering temperature(1250℃, 1300℃, 1350℃), analyze the difference in microwave properties. In the following conditions: x=3, 1300℃/4 hours, the microwave ceramics have permittivity=92 and dielectric loss=112
