Method for preparing intermetallic compound of Ni3Al using aluminium chloride and intermetallic compound of Ni3Al prepared by the same

摘要

the present invention, Ni and Al powder for a green sheet produced from a mixture which comprises a step (S1); Removing the organic material from the green sheet was placed in the reactor the green sheet (S2); And the step of the green sheet was added to the aluminum chloride is reacted with the aluminum chloride as an activator into the reactor (S3); Ni with aluminum chloride, characterized in that it comprises a ₃ Al intermetallic compound the production method and hence the Ni ₃ Al provides an intermetallic compound. Ni with aluminum chloride according to the present invention ₃ Al intermetallic compounds can be prepared at a low temperature of below the melting point of Ni and Al. In addition, Ni using aluminum chloride in accordance with the present invention ₃ Al intermetallic compound has a high economic value because the Ni and Al powder made from cheap. Furthermore, Ni ₃ Al intermetallic compound microstructure control is more easily and thus the catalyst support and catalyst in a ball mill by the method and a tape casting process in the manufacture of a green sheet using aluminum chloride in accordance with the present invention It is also possible to take advantage of its own.
