A Research on the Effects of Heat Treatment on the Breakdown Characteristics of Amber Miea

호박운모의 절연파괴특성에 미치는 열처리의 영향에 관한 연구

The contents of this paper are the effects of heat treatment on the breakdown strength of Amber Mica. In this study the breakdown strength of Amber Mica of which thickness is about 0.2-0.5(mm) was found to be raised by approximately 10% when it is heat treated at proper temperature and during suitable interval of time. Furthermore, both the heat-treatment temperature and time interval are higher and longer respectively within some extent, the more breakdown strength increasing effects are able to be expected. The results of this experiments are explained qualitively by the existence of contained gas, Hippel's breakdown theory in crystal solid insulator, and disorder of crystal structure.
