Zusammenfassung:	PURPOSE: A method is provided to prevent an implosion and reduce the thickness and weight of a panel glass by performing an ion exchange process in a certain part of a glass bulb region where the maximum tension stress affects. CONSTITUTION: A method comprises a step of performing an annealing process for forming a thermal residual stress layer on a surface of a panel; and a step of partially forming a composite layer having an ion exchange layer having a stress larger than a thermal residual stress, by coating an ion exchange slurry to the region where the maximum tension stress affects. The ion exchange slurry is obtained by mixing potassium nitrate and zinc oxide. 본 발명은 음극선관 유리벌브용 패널의 제조방법에 관한 것으로서, 더욱 상세하게는 용융유리로부터 성형되어진 음극선관 유리벌브용 패널에 최대인장응력이 발생하는 특정 영역 즉, 가장 약한 영역에 질산칼륨 용액과 산화아연 분말을 혼합한 이온교환용액 슬러리로 피복시켜 유리 표면에 압축응력을 형성시킴으로써 종래보다 폭축의 발생을 억제함은 물론 강화된 패널 유리의 박형화 및 경량화가 가능한 음극선관 유리벌브용 패널의 제조방법에 관한 것이다.
