Preparation of thin ceramic monofilaments for TEM observation with novel embedding processes

►We develop an applicable method to prepare TEM specimens from thin ceramic fibers. ►We develop novel embedding processes to enhance the polishing efficiency. ►A self-manufactured device is used to get uniformly low thickness. ►One-side dimpling method and calculated ion milling process are introduced. ►Samples with large thin area for longitudinal and cross-sectional view are obtained.
