초록

전력저장용 전기에너지 저장장치의 일종인 NaS 전지 단위 셀을 개발함에 있어서 알파-알루미나 절연세라믹 캡과 베타-알루미나 전해질 튜브 간의 세라믹-세라믹 상호 접합을 위하여 글라스 기반의 실링소재가 필요하다. 본고에서는 이 세라믹-세라믹 접합용 글라스 실링 페이스트를 제조함에 있어서, 열간 칭법에 의한 글라스 프릿 제조와 상분석, 분말입도 분석 및 글라스 조성에 따른 열팽창계수 변화 및 표면거칠기를 분석하였다. 또한 글라스 실란트의 접합력 평가를 위해 종래 솔더 볼 조인트의 접합력 평가용 분석장비인 Dage bond tester를 이용하여 세라믹-세라믹 컴포넌트의 작은 접합면에 대한 접합력 측정 방법을 제안하였다.

Glass base sealant is required as a ceramic-ceramic joining material between α-alumina insulation cap and β-alumina electrolyte tube in the development of NaS battery cell package for electrical energy storage system. The fabrication of glass frit by thermal quenching method, phase analysis, particle size analysis, coefficient of thermal expansion and surface roughness according to the glass compositions were analyzed for the fabrication of glass sealing paste for ceramic-ceramic joining. Also, a new evaluation method of the adhesion strength of glass sealant at the small area in ceramic-ceramic joining component was proposed using conventional Dage bond tester that was used to measure the adhesion of solder ball joint.
