中文摘要 | 本實驗是利用真空預燒結的方式將0.07PMnN-0.468PZ-0.462PT壓電陶瓷的緻密性提升,並在800°C下破真空以空氣氣氛燒結避免大量的鉛揮發的產生。由室溫抽真空並加溫至800°C破真空後直接升溫至1050°C持溫1小時有最佳的壓電特性與相對密度的表現,此時的Qm可達2050且kp亦可維持在0.613。有真空預燒結的製程在燒結溫度方面有明顯的下降,且較傳統燒結流程下降約150°C。 |
英文摘要 | Pre-sintering in vacuum was used to enhance the densification of sintered 0.07PMnN-0.468PZ-0.462PT certamics in this study. This pre-sintering process was to heat the samples from room temperature to 800°C under 102torr vacuum condition. When temperature reaches 800°C, air with ambient pressure conducted into the chamber, in the mean time, the samples were continuously heated to 1050°C for various holding periods. In the case of holding 1 hour, best combination piezoetectric properties of this ceramics were obtained, where Qm and kp was 2050 and 0.613 respectively. Comparing with conventional sintering process, this pre-sintering process can lower sintering temperature up to 150°C without deteriorating piezoelectir properties of these ceramics. |
