ABSTRACT:
The present invention discloses a mold and a method of manufacturing the mold. The mold includes a mold matrix and a number of boron nitride nanotubes sintered together with the mold matrix. Each boron nitride nanotube capsules a number of fullerenes therein respectively. The mold further includes an amount of noble metal powder sintered together with the mold matrix and the boron nitride nanotubes. The fullerenes preferably include C60molecules. In addition, the method for manufacturing a mold includes the steps of: providing a number of boron nitride nanotubes, each boron nitride nanotube capsuling a number of fullerenes therein respectively; mixing a mold matrix with the boron nitride nanotubes capsuling the fullerenes to form a complex; molding the complex to form a mold preform; and sintering the mold preform, thereby attaining a mold.
