Low viscosity filler composition of boron nitride particles of spherical geometry and process

摘要

A low viscosity filler boron nitride agglomerate particles having a generally spherical shape bound together by an organic binder and to a process for producing a BN powder composition of spherically shaped boron nitride agglomerated particles having a treated surface layer which controls its viscosity.

1. A composition consisting essentially of:
spherical agglomerated boron nitride particles comprising irregular shaped boron nitride particles bound together by an organic binder in a generally spherical geometry, the spherical agglomerated particles having an average diameter of about 10 microns or greater, a tap density of from about 0.287 to about 0.631 g/cc, and a surface layer of the organic binder and/or decomposition product thereof.
