Titan산 Barium Ceramic Capacitor의 시작

Fabrication of Barium Titanate Ceramic Capacitors

강유전재료로서 가장 대표적이며 전자부품으로서 많이 사용되는 것 중의 하나인 titan 산 barium 자기 capacitor의 제조방법과 그 특성을 기술하였다. 산화 titanium과 탄산 barium을 1:1 mole비로 하고 이에 몇가지의 광화제를 첨가해서 소성한 어떤 자기결정의 전기적특성은 표준치와 잘 일치하였으며 절록저항, 온도계수 및 흡수율은 일반적으로 볼 수 있는 치를 많이 넘었다. 이러한 특성을 낼 수 있는 적당한 제조방법을 알아낼 수 있었다.

The fabrication of the barium titanate ceramic capcitors has been studied. The effects of the impurities for alumina and silica upon mechanical and electrical characteristics have been examined in detail. The preparation of equimolar titanium oxide and barium carbide in addition two percent of alumina and point two five perdcent of silica has shown the best results. This is fired up to thirteen hundred degrees Celsius with the rate of two hundred degrees Celsius per hour and soaked three hous at this temperature. The dielectric constant of this sample is approximately equal with the standard and theoretical values at room temperature. The insulation resitances of the most fabricated capacitors are in the order of twenty thousand megohms, the dielectric constant and the dissipation factor are almost flat up to just below of curie temperature, and the porosities of the most ceramics are less than point one percent and well close or equal to zero percent.
