pH meter의 사용법
1. pH meter의 원리
pH meter는 두 전극이 연결된 전기화학기기이다. 이 두 전극 중 하나는 비교전극(reference electrode)으로서 직접 용액에 접촉하게 되어 있고 다른 하나는 유리전극(glass electrode)으로서
modifier가 첨가된 alumino-silicate 계열의 유리 재료들이 PDP의 기판 유리 재료로서 사용되고 있다. 현재 PDP 공정의 경우, 대부분이 소성 온도가 560~590℃의 범위에 있기 때문에 연화(softening) 온다가 570℃인 alumino-silicate 유리 재료를 채용하고 있다.
