Example Embodiment
[0028] Example 1:
[0029] The scandium nitrate aqueous solution and the zirconium nitrate aqueous solution are mixed to obtain a scandium-zirconium mixed solution; after the scandium-zirconium mixed solution is atomized into fine droplets, they are carried into the high-temperature reaction furnace by the flow of carrier gas. It goes through the steps of solvent evaporation, solute precipitation, drying, metal salt thermal decomposition and sintering in order, and finally the scandium zirconium powder is formed. Wherein, the cation concentration in the scandium-zirconium mixed solution is 0.5 mol / L, and the number of moles of scandium ions is 8% of the total number of moles of scandium ions and zirconium ions. The ultrasonic nozzle power is 30W, the carrier gas flow rate is 30L / min, and the spray pyrolysis temperature is 1200℃.
Example Embodiment
[0030] Example 2:
[0031] The scandium chloride aqueous solution and the zirconium oxychloride aqueous solution are mixed to obtain a scandium-zirconium mixed solution; after the scandium-zirconium mixed solution is atomized into fine droplets, they are carried into the high-temperature reaction furnace by the flow of carrier gas, and after the droplets enter the reaction furnace, In a relatively short period of time, the steps of solvent evaporation, solute precipitation, drying, metal salt thermal decomposition and sintering are successively passed through, and finally scandium zirconium powder is formed. Wherein, the cation concentration in the scandium-zirconium mixed solution is 5 mol / L, and the number of moles of scandium ions is 10% of the total number of moles of scandium ions and zirconium ions. The ultrasonic nozzle power is 15W, the carrier gas flow is 20L / min, and the spray pyrolysis temperature is 1400℃.
