실험 절차
A cerium oxalate powder was prepared by adding an aqueous solution of ammonium oxalate to an aqueous solution of cerium chloride under stirring, causing the precipitation of cerium oxalate, filtering, and drying. The powder was ground with a jet-mill to obtain a starting material powder with a mean particle diameter of about 1 μm. The powder was ejected at a feed rate of 5 kg/hr through a nozzle with a cross-sectional area of the opening of 0.13 cm2 together with air at a flow rate of 200 L/min as a carrier gas into a reaction tube heated to a temperature of 1500° C. in an electric furnace, passed through the reaction tube, while maintaining the dispersion concentration of the powder, and heated. The melting point of cerium oxide is about 1950° C. The dispersion concentration of the starting material powder in the gas phase inside the reaction tube was 0.4 g/L, and V/S was 1500. The light-yellow powder thus produced was collected with a bag filter.
