BORNITRID-AGGLOMERATE, VERFAHREN ZU DEREN HERSTELLUNG UND DEREN VERWENDUNG
The invention relates to boron nitride agglomerates, comprising hexagonal boron nitride primary particles, wherein the hexagonal boron nitride primary particles are connected to one another by means of an inorganic binding phase comprising at least one nitride and/or oxynitride. The invention also relates to a method for producing such boron nitride agglomerates, wherein boron nitride starting powder in the form of boron nitride primary particles is mixed with binding-phase raw materials, processed into granules or molded bodies and these are then subjected to a temperature treatment at a temperature of at least 1000° C. in a nitriding atmosphere, and the obtained granules or molded bodies are comminuted and/or fractionated if necessary. The boron nitride agglomerates according to the invention are suitable as a filler for polymers to be used for producing polymer-boron nitride composite materials.
