SPINEL-BASED OXIDES CONTAINING MAGNESIUM, ALUMINUM AND TITANIUM AND METHODS OF FORMING ARTICLES HAVING SAME

Abstract:

The disclosed technology generally relates dielectric materials, and more particularly to a combination of co-fireable dielectric materials that can be attached to each other without the use of adhesives. In an aspect, a composite article comprises a magnetic portion comprising a nickel zinc ferrite. The composite article additionally comprises a non-magnetic portion contacting the magnetic portion, the non-magnetic portion comprising a spinel-structured oxide comprising Mg.sub.2-xAl.sub.2xTi.sub.1-xO.sub.4 and having a dielectric constant between about 7 and 14, wherein 0<x.ltoreq.1.
