Abstract:
A method of synthesizing aluminum nitride, the method includes: preparing mixed powder containing 0.5 to 8 wt % of zinc powder, 0.01 to 2 wt % of magnesium powder, 0.01 to 1 wt % of silicon powder, 0.01 to 1 wt % of copper powder, and a balanced amount of aluminum powder; preparing a feedstock of the mixed powder blended and filled with thermoplastic organic binder, by pressured kneading the mixed powder and the thermoplastic organic binder; forming granules of the feedstock by crushing the feedstock or forming a molded body of the feedstock via a powder molding method; and debinding the granules or the molded body by heating under a nitrogen gas atmosphere, and then performing direct nitridation between aluminum and a nitrogen gas at a temperature higher than a debinding temperature.

Claim (Index 12):
A method of synthesizing an aluminum nitride-based composite material, the method comprising:\n preparing mixed powder containing 0.5 to 8 wt % of zinc powder, 0.01 to 2 wt % of magnesium powder, 0.01 to 1 wt % of silicon powder, 0.01 to 1 wt % of copper powder, and a balanced amount of aluminum powder, and then adding 0.1 to 10 wt % of at least one element selected from the group consisting of lithium, calcium, phosphorous, gadolinium, iron, nickel, cobalt, manganese, silver, chromium, zirconium, strontium, molybdenum, tungsten, and alloys thereof to the mixed powder to obtain 100 wt % of a powder mixture; preparing a feedstock packed as the powder mixture and a thermoplastic organic binder are mixed, by pressurizing and kneading the powder mixture and the thermoplastic organic binder; forming granules of the feedstock by crushing the feedstock or forming a molded body of the feedstock via a powder molding method; and debinding the granules or the molded body via heating under a nitrogen gas atmosphere, and then performing direct nitridation between aluminum and a nitrogen gas at a temperature higher than a debinding temperature.
