Agglomerated hexagonal boron nitride powders, method of making, and uses thereof

   
   

The present invention relates to a powder including agglomerates of hexagonal boron nitride platelets, wherein the agglomerates have an agglomerate size distribution of from about 10 to about 125 microns and the powder is substantially free of non-agglomerated platelets of boron nitride and its use in a polymer blend. The present invention also relates to a method of making a powder including agglomerates of hexagonal boron nitride platelets. This method involves providing a briquette formed from agglomerated hexagonal boron nitride platelets, crushing the briquette to produce a powder including hexagonal boron nitride agglomerates and non-agglomerated boron nitride platelets, and removing the non-agglomerated boron nitride platelets from the powder under conditions effective to produce a powder including agglomerates of hexagonal boron nitride platelets having an agglomerate size distribution of from about 10 to about 125 microns.
