Beschreibung
Zusammenfassung:	A boron nitride composition having its surface treated with a coating layer comprising at least one of a silane, a siloxane, a carboxylic derivative, and mixtures thereof, wherein the coating layer adheres to at least 10 % of the surface of the boron nitride. The boron nitride powder surface is first treated by either a calcination process, or by coating with at least an inorganic compound for the surface to have a plurality of reactive sites containing at least a functional group that is reactive to at least one functional group of the final coating layer.
