Abstract
Boron nitride green sheets are made of boron nitride powder in an organic binder which leaves no undesirable residue upon pyrolysis in the absence of oxygen. These boron nitride green sheets can be placed on each side of the ceramic green sheet to form a composite for hot pressing ceramic green sheets containing ceramic powder to produce dense ceramic sheets suitable for electronic substrates.
