氧化物包覆磁性吸收剂的研究进展

Research Status and Development of Oxide Coatings for Magnetic Absorbents

阐述了近年来氧化物包覆磁性吸收剂的研究动态,总结了二氧化硅、氧化铝、二氧化钛、氧化锌等包覆层最新研究进展。通过研究发现,轻质、耐高温、介电常数低的氧化物用于包覆磁性金属具有诱人的应用前景。

The recent development of oxide coatings for magnetic absorbents is summarized. The lastest pro gress of protective shells of silicon dioxide, alumina, titanium dioxide, and zinc oxide is mainiy reviewed. Due to low density, oxidation resistance, and low permittivity, they have a promising applications for coating magnetic absorbents.
