本文主要探討各種摻雜物,例如NiO, Fe2O3, Cr2O3, Sb2O3等,對鈦酸鋇陶瓷的微結構及介電特性之影響。文中探討摻雜離子價數對鈦酸鋇陶瓷介電常數的燒結溫度特性、介電損等參數的影響。由實驗結果可知適當的摻雜量可控制晶粒成長,減少介電損,改變介電常數。
各組成介電常數與測量頻率之間的關係,由結果可知,當摻雜3wt%Sb2O3之粉末時,頻率在小於100KHz,介電常數會隨著頻率的增加而減少,當頻率大於100KHz時,介電常數會頻率增加而增加,而其他無論是那一種組成均有相同的趨勢,隨著頻率的增加介電常數有減少的趨勢。在燒結溫度方面,相同測量頻率下,當摻雜3wt%Sb2O3之粉末時,燒結溫度在1300℃,其介電常數會比在1250℃燒結時還來的小,但燒結溫度提升至1350℃時,介電常數就會增加,而其他各種組成皆會因燒結溫度的增加,使相同測量頻率之介電常數跟著減少。
在介電損方面,在相同的燒結溫度下隨著頻率的增加,摻雜3wt% Cr2O3的陶瓷體其介電損較純鈦酸鋇為大,而各摻雜3wt% Fe2O3及3wt%Sb2O3的陶瓷體其介電損較純鈦酸鋇為小。
因此,Fe2O3的摻雜會讓燒結溫度降低,介電損減少;NiO會降低燒結溫度,但其變化性太大,製作過程不易控制;Sb2O3的摻雜會降低燒結溫度,提高介電常數,減少介電損,對鈦酸鋇而言是一種很好的摻雜物; Cr2O3摻雜會降低整體鈦酸鋇的特性,燒結溫度的增加,介電常數的減少,介電損的增加,都是不好的影響。
The influence of different dopant; such as NiO, Fe2O3, Cr2O3, Sb2O3 on the microstructure and dielectric properties, including sintering temperature dependence of permittivity, dielectric losses, has been investigated on BaTiO3 ceramics. Experiments reveal that incorporation of a proper content of dopant can control the grain growth, reduce the dielectric losses, and significantly improve temperature characteristics of the BaTiO3 ceramics. The experimental result, the dopant amount can control the crystalline grain grow up , change the loss tangent and dielectric constant.
When addition of 3wt% Sb2O3 dopants , frequency is smaller than 100KHz, the dielectric constant will be reduced with increase of frequency, when frequency greater than 100KHz, dielectric constant can increase and the frequency increase; Other of the dopant have the same trend, the dielectric constant will be decrease when frequency increase.
In the sintering temperature, measure it under frequency at the same, when addition of 3wt% Sb2O3 dopants, the sintering temperature in 1300℃,its dielectric constant will be smaller than ones that stilled come when 1250℃, but sintering temperature improve to 1350℃, the dielectric constant will be increase; The various kinds of components are increase of sintering temperature, and have the dielectric constant is reduce which the same measures frequency.
In dielectric losses, with the increase of frequency under the same sintering temperature, addition of 3wt% Cr2O3 dopants, the dielectric losses is greater than BaTiO3 , and addition of 3wt% Sb2O3 and Fe2O3 dopants , the dielectric losses is smaller than BaTiO3.
So addition of 3wt% Fe2O3, can reduce the sintering temperature , the dielectric losses and dielectric constant will be decrease; Addition of 3wt% NiO will reduce the sintering temperature, but its change is too great, the making course is not easy to control ; Addition of 3wt% Sb2O3 will reduce the sintering temperature, improve the dielectric constant, reduce dielectric losses; Addition of 3wt% Cr2O3 is it can reduce characteristic of BaTiO3, increase of sintering temperature and the dielectric losses, reduce of the dielectric constant.
