采用超声波震荡-静置法制备前驱体溶液,随后采用水热合成法,通过改变溶液pH值、合成温度及填充率等条件,制备出超细稀土掺杂MoO3粉末,最后采用二段氢还原法制备出纳米稀土掺杂Mo粉。利用XRD、SEM等手段对合成的MoO3产品进行结构表征。结果表明,在溶液pH值0.5、合成温度180℃、填充率90%的条件下进行合成时,所制得纳米稀土Mo粉细小均匀、具有良好的分散性。 The precursor solution was prepared by ultrasonic vibration-static method. Then the hydrothermal synthesis method was used to prepare ultrafine rare earth doped MoO3 powder by changing the solution pH, synthesis temperature and filling rate. Finally, Preparation of nano rare earth doped Mo powder. The structure of the synthesized MoO3 was characterized by means of XRD and SEM. The results show that when the solution is synthesized at a solution pH value of 0.5, a synthesis temperature of 180 ° C and a filling rate of 90%, the nano-rare earth Mo powder is fine and uniform and has good dispersibility.
