本文主要在探討鋅鈮鋯鈦酸鉛鐵電陶瓷系統透過改質在低溫燒結時的壓電特性，運用低溫材料系統完成多層壓電陶瓷元件，並保有一定壓電特性，進而應用在生活周遭多方面之元件。低溫燒結使得材料選用及能源成本大幅降低， 添加適量的Li2CO3當助燒劑使用，並探討不同成份下的鐵電、壓電等特性，設計出優良致動材料系統。
研究主要成分為0.3 Pb(Zn1/3Nb2/3)O3 – 0.7 Pb(Zr0.52Ti0.48)O3 添加0.3~0.9wt%的Li2CO3為助燒結劑，由燒結溫度和密度量測可得知，選用最佳的0.6wt%添加量並在900°C燒結持溫6小時，能夠得到最佳性質及溫度燒結等，將促進燒結速率和緻密化，壓電性質量測方面在鋅鈮酸鉛含量為30 mole％以及助燒結劑添加0.6wt%的Li2CO3，試片同時存在菱方晶與正方晶相，且晶粒大小(1.82 μm)具有最大的機電耦合係數(72.6％) ，顏色呈現淡黃色，且高緻密化甚至能夠透光，其相對密度高達95%以上，其中的Li+ 離子置換PZNZT系統之中的Zn2+形成硬改質添加，形成氧空缺而提高矯頑電場，在改質後的系統中矯頑電場 (14 kV/cm)，平均殘留極化值維持在（40 μC/cm2）同時此材料系統在塊材的應變量表現也相當優異，應變約莫為0.35%。另一優勢為高的居禮溫度(約260~280℃)更是0.3PZNZT+(0.3~0.9)wt% Li2CO3之優勢，可克服元件在工作時所自發產生的熱或者高溫之工作環境，預期使用在致動元件上的需求更加符合。
多層元件使用改質後陶瓷粉末搭配業界常見漿料配製所需薄帶，並進行網印、疊壓、切割、燒結等製程後，完成最終多層元件，同時透過TGA檢測得到相關燒結參數並完成多層陶瓷薄帶與銀電極於900℃之燒結，由EDS分析可以得知，多層陶瓷元件在傳統燒結發現會有局部銀擴散問題及漏電流之情況產生，使用微波燒結爐在相同溫度下燒結有效控制銀電極擴散，不論是微觀下或是性質表現上，其壓電常數d33為440pC/N，較塊材有所下降，在施以45kV/cm(270V)的電壓可達到0.2%的應變量並克服傳統燒結無法達到所需性質的問題。
0.3 Pb(Zn1/3Nb2/3)O3 – 0.7 Pb(Zr0.52Ti0.48)O3 + 0.6wt%Li2CO3完成改質後發現Qm品質因子較低(約60)， 電能和機械能轉換時容易自身發熱，造成材料內部達到高溫，甚至超過居禮溫度以上，材料轉變成順電相，使材料電的特性下降，故品質因子也是元件所重視的特性之一，所以透過Mn硬改質添加在原材料系統中，使材料系統Qm有效的提升(至175)。

This paper mainly discusses the piezoelectric properties of lead-zinc-zirconium titanate titanate lead-based ceramic system through low-temperature sintering, the use of low-temperature material system to complete multi-layer piezoelectric ceramic components, and maintain a certain piezoelectric properties, and then used in the life of more Aspects of the components. Low temperature sintering to make use of materials and energy costs significantly reduced, add the appropriate amount of Li2CO3 when the use of combustion agent, and explore the different components of the ferroelectric, piezoelectric and other characteristics, the design of excellent actuating material system.
0.3Pb(Zn1 / 3Nb2 / 3) O3 - 0.7 Pb (Zr0.52Ti0.48) O3 is added as 0.3% to 0.9wt% of Li2CO3 as the sintering agent. It can be seen from the sintering temperature and density measurement. The best content of 0.6wt% and the sintering temperature at 900 ° C for 6 hours, can get the best properties and temperature sintering, etc., will promote the sintering rate and densification, piezoelectricity test in the zinc lead niobate content (72.6%) with the largest grain size (1.82 μm), the color of which was yellowish, and the color was yellowish, And high densification can even light transmission, the relative density of up to 95% or more, of which Li + ion replacement PZNZT system of Zn2 + formed by hardening modified to form the oxygen vacancy and improve the coercive field, in the modified system (14 kV / cm), the average residual value is maintained at (40 μC / cm2) while the strain rate of the material system in the block is also quite excellent Strain (0.35%), the other advantage is high Ritual temperature (average 280 ℃) is 0.3PZNZT + (0.3 ~ 0.9) wt% Li2CO3 advantage, can overcome the yuan The work of the heat generated by the heat or high temperature of the working environment, is expected to use the components on the demand for more consistent.
Multi-layer components using modified ceramic powder with the industry common slurry configuration required strip, and screen printing, stacking, cutting, sintering and other processes, the completion of the final multi-layer components, while TGA detection by the relevant sintering parameters and complete multi-layer Ceramic strip and silver electrode at 900 ℃ sintering, EDS analysis can be learned, multi-layer ceramic components in the traditional sintering found that there will be partial silver problems and leakage current situation, the use of laboratory microwave sintering furnace at the same temperature Sintering effective control of silver electrode diffusion, whether microscopic or the performance of the performance, the piezoelectric constant d33 is 440pC / N, compared with the block material decreased, in the application of 45kV / cm (270V) voltage can reach 0.2% Adaptable and successfully overcome the above problems.
0.3Pb(Zn1/ 3Nb2 / 3) O3 - 0.7 Pb (Zr0.52Ti0.48) O3 + 0.6wt% Li2CO3 After the modification, it is found that the Qm quality factor is low (about 60), and the energy and mechanical energy , Resulting in high temperature within the material, or even more than the temperature above the house, the material into a cis phase, so that the characteristics of the material decreased, so the quality factor is also a component of the importance of one of the characteristics, so hardened by Mn added to the raw material system , The material system Qm is effectively raised (to 175).
