Abstract
Disclosed are methods for forming boron nitride-containing aggregates that exhibit improved wear by attrition, and resulting filled polymers that exhibit significantly improved thermal conductivity. The boron nitride-containing aggregates are prepared according to a method that includes wet granulating boron nitride powder with a granulation solution to form wet boron nitride-containing granules; and drying the wet boron nitride-containing granules to cause evaporation of solvent in the granulation solution, thereby forming boron nitride-containing granules. Sintering achieves the desired boron nitride-containing aggregates.
Claims32
A method for forming boron nitride-containing granules comprising:
- wet granulating boron nitride powder with a granulation solution to form wet boron nitride-containing granules;
- and
- drying the wet boron nitride-containing granules to cause evaporation of solvent in the granulation solution, thereby forming boron nitride-containing granules.
The method according to claim 115 or 16, wherein said wet granulating is carried out with a liquid:solids ratio (by volume) of between about 0.1:1 to about 0.5:1.
