Abstract
A boron nitride composite is proposed. The boron nitride composite may include an aggregate including a plurality of boron nitride particles bonded to each other to form a plurality of pores. The boron nitride composite may also include a filler containing at least one of an organic material or an inorganic material, and filled in at least some of the plurality of pores such that the organic material and the inorganic material do not cover an outer surface of the aggregate.
Claims13
A boron nitride composite comprising:
- an aggregate including a plurality of boron nitride particles bonded to each other to form a plurality of pores;
- and
- a filler containing at least one of an organic material or an inorganic material, and filled in at least some of the plurality of pores such that the organic material and the inorganic material do not cover an outer surface of the aggregate.
A method of preparing a boron nitride composite, the method comprising:
- preparing slurry in which slurry is prepared by adding at least one of a main material, a curing agent, or acetone to an aggregate formed with a plurality of boron nitride particles bonded to each other and stirring the aggregate;
- removing a solvent in which the slurry is depressurized to remove the acetone and a boron nitride filler mixture is formed;
- semi-curing the boron nitride filler mixture;
- removing a filler on an outer surface in which the semi-cured boron nitride filler mixture is put into the solvent and stirred to remove a filler on the outer surface of the semi-cured boron nitride filler mixture;
- and
- preparing a composite in which, after removing the filler on the outer surface, the boron nitride filler mixture is cured for a predetermined time and fired for a predetermined time to form a boron nitride composite.
