PROBLEM TO BE SOLVED: To provide novel boron nitride agglomerated powders having controlled density and fracture strength features, and a method for producing the novel boron nitride agglomerated powders. SOLUTION: The method needs preparing a feedstock powder including boron nitride agglomerates, and heat treating the feedstock powder to form a heat treated boron nitride agglomerated powder. In one embodiment, the feedstock powder has a controlled crystal size. In another, the feedstock powder is derived from a bulk source. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To relate to modified thermally conductive powder or particles having hydrophobic coating layer substantially on the whole surface and to provide a moisture-resistant thermally conductive material. SOLUTION: A moisture resistant thermally conductive material comprising a particulate filler comprising thermally conductive particles having a hydrophobic compound coating and a binder effective to join together the filler particles. The present invention also includes an electronic apparatus comprising a heat source (12), a heat sink (14), and a layer (16) of the moisture resistant, thermally conductive interface material disposed between and in contact with the heat source (12) and the heat sink (14). Still, the present invention is directed to a moisture resistant, thermally conductive material comprising particles of agglomerated boron nitride having a hydrophobic compound coating. Yet, the present invention includes a method of removing heat from a heat source comprising providing a heat sink proximate the heat source and disposing a layer of the moisture resistant, thermally conductive material between and in contact with the heat source and the heat sink.

PROBLEM TO BE SOLVED: To provide a powder comprising boron nitride particles having an aspect ratio of from about 50 to about 300; and to provide a method of making a delaminated hexagonal boron nitride powder. SOLUTION: The method involves providing a boron nitride powder and milling the boron nitride powder in a mixture including a milling medium and a milling liquid under conditions effective to produce the delaminated boron nitride powder. An extrusion method of a molten polymer is also provided. The method comprises blending a powder containing hexagonal boron nitride particles having an aspect ratio of from about 50 to about 300 with a polymer to form a blend, and obtaining an extruded product by extruding the blend through an extruder under conditions effective to disperse the boron nitride particles in the whole polymer.
