Abstract

The invention relates to boron nitride agglomerates, comprising lamellar, hexagonal boron nitride primary particles, which are agglomerated with one another with a preferred orientation, the agglomerates formed being flake-shaped.The invention also relates to a method for producing said boron nitride agglomerates, characterized in that lamellar, hexagonal boron nitride primary particles are agglomerated in such a way that they line up with one another with a preferred orientation.The flake-shaped agglomerates according to the invention are suitable as filler for polymers for making polymer-boron nitride composites and for hot pressing of boron nitride sintered compacts.
