  • Patent number: 10442692
    Abstract: The present invention relates to a method of manufacturing aluminum nitride and aluminum nitride prepared by the same. Pure aluminum powder having a median particle size (D50) of 1.52 ?m was heated to a temperature in a range of 595° C.˜900° C. in a nitrogen containing atmosphere comprising nitrogen and argon gases, at atmospheric pressure for one hour to obtain aluminum nitride with a degree of nitridation exceeding 93%. According to the present invention aluminum nitride may be produced with high yield using a simple and inexpensive one-step heating method in a relatively short period of time.
    Type: Grant

  • Patent number: 10094006
    Abstract: The present invention is related to a method of fabricating an aluminum matrix composite by a simple process of heating a mixture of a ceramic reinforcing phase and aluminum in nitrogen containing atmosphere and an aluminum matrix composite fabricated by the same. The aluminum matrix composite may be fabricated by heating to temperatures even lower than the melting temperature of aluminum as well as to temperatures higher. The exothermic nitridation reaction contributes to the melting of the aluminum matrix and the aluminum nitride formed in-situ as a result may act as an additional reinforcing phase.
