Abstract
A molten iron-assisted method for producing aluminum nitride (AlN) and a device thereof are disclosed. Pure aluminum is introduced into a vacuumed molten iron bath continuously for producing a molten iron bath having the aluminum, then nitrogen is introduced into the molten iron bath having the aluminum. Production of AIN is controlled by having the concentration of aluminum in the molten iron bath having the aluminum controlled. At the time AIN is formed continuously in the molten iron bath having the aluminum, AIN floats to the surface of the molten iron bath having the aluminum. Ar and Nmay be blown and dust is removed by static electrons thereafter, such that pure aluminum nitride powder can be collected. Finally, the used gas is recycled and reused.
