Abstract: The purpose of this report is to demonstrate the impact of process and materials variables on the characteristics of a Curie-limited susceptor based upon Co(2-2x)Zn2xBa2Fe12O22 formed using a solution-processing approach. Zn2Ba2Fe12O22 (Zn2Y) was the focus of this report, which has a Curie temperature of approximately 130 ¿C. The prepared particles were characterized using x-ray diffraction, environmental-scanning microscopy, x-ray photoelectron spectroscopy, and a vibrating sample magnetometer (VSM). Some basic observations and experimental results are provided for each method. VSM was determined to be among the most sensitive methods for characterization. Process variations produced significant product variations, but sources and causes were not fully isolated through this study. An ongoing effort to determine process controls for optimization and scale-up of particle processing of zinc-based compounds will be the focus of future works.
