Fabrication method of ternary nano type Al oxide core powder by spray pyrolysis

摘要

Provided is a method for manufacturing ternary aluminum oxide core nanopowder using a spray pyrolysis method having a uniform particle shape, not causing agglomeration, and capable of easily controlling a particle size and freely controlling the composition of metal components. The manufacturing method comprises a step of manufacturing a spray solution by adding a particle inflating agent for controlling a particle shape, such as EDTA(C_10H_16N_2O_8) and CA(C_6H_8O_7), to distilled water after melting iron salt and aluminum salt in the distilled water; collecting powder from the manufactured spray solution after the spray solution is synthesized to the powder using a spray pyrolysis method; and then pyrolyzing the collected powder.
