Abstract

SrZrO$_3$ resistive oxides on Ag tapes were prepared by the sol-gel and dip coating method to investigate the effect of PVP content and drying condition on microstructure of the films. Although the film thickness increased with the addition of PVP, the amount of PVP and heat treatment were not effective to reduction of formation of microcracks at the films. However, lower drying temperature and longer drying time were beneficial to control the microcracks of the SrZrO$_3$ films, indicating that the microcracking of the films was governed primarily by the drying condition.

은(Ag) 선재 위에 SrZrO$_3$ 절연 산화물을 졸-겔과 딥-코팅법으로 제조하여 박막표면의 미세균열에 미치는 PVP 함량과 건조조건 영향을 조사하였다. PVP 함량이 증가할수록 박막 두께는 증가하였지만, PVP 함량과 열처리 온도는 박막 표면의 미세균열에 영향을 미치지 못 하였다. 하지만, 낮은 건조온도와 긴 건조시간은 SrZrO$_3$ 박막 미세균열에 영향을 주었다. 그러므로, SrZrO$_3$ 코팅층 표면의 미세조직은 건조조건에 의하여 결정되는 것으로 관찰되었다.
