Metallization of ferrites comprising surface reduction |
摘要 |
<p>The present invention provides a method for metallizing a ceramic body (10) comprising a ferrite through a surface reduction treatment. A ceramic body comprising a ferrite is heated. At least a portion of the ferrite is contacted with a gaseous reducing agent to create a metallic region by removing oxygen from the ferrite. The surface is cooled and, optionally, post-treated to enhance adhesion of the metallic region. Typical gaseous reducing agents are hydrogen, forming gas, and ammonia while typical ferrites are nickel-zinc ferrites and manganese-zinc ferrites. To form patterned regions, portions of the substrate are masked or portions of the reduced layer are removed.</p> |
