Abstract
The invention discloses a hydrothermal synthetic method of nano yttrium oxide powder. The hydrothermal synthetic method comprises the following steps: (1) firstly adding pentaerythritol to a yttrium nitrate solution; (2) then adding a sodium hydroxide solution to the solution in the step (1), adjusting the pH value of the solution to be 11-13 and then reacting at 170-200 DEG C for 20-30 hours; (3) filtering the filtrate in the step (2) and washing, drying and calcining the filter residues to obtain the nano yttrium oxide powder. Compared with existing methods, the method has the advantages that the nano yttrium oxide powder obtained by adopting the method is a sphere with homogeneous morphology, and the grain size of the nano yttrium oxide powder can be controlled to be 45-55nm.
