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

摘要

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_2-xAl_2xTi_1-xO₄ and having a dielectric constant between about 7 and 14, wherein 0x≤1.
