Abstract
The present invention discloses the synthetic method of a kind of nano yttrium oxide powder, comprises the steps: that (1) first adds glycerol in acetic acid yttrium solution；(2) adding sodium hydroxide solution again in the solution of step (1), regulation pH value of solution, to 11 13, then reacts 20 30 hours at 170 200 DEG C；(3) step (2) reacting liquid filtering, filtering residue is scrubbed, dry, obtain nano yttrium oxide powder after calcining.Compared with the conventional method, the nano yttrium oxide powder using the inventive method gained is homogeneous spherical of pattern, and size tunable system is at 20 35nm.
Description
Technical field
The present invention relates to the synthetic method of a kind of nano yttrium oxide powder.
Background technology
Yittrium oxide (Y2O3) it is a kind of important rare earth compound, there is thermostability, corrosion resistance, high-k and a series of excellent optical property of uniqueness, be widely used in the fields such as advanced ceramic, photoelectric device, catalyst.
In recent years, preparation to nano yttrium oxide powder both at home and abroad expands and studies widely, and main preparation methods includes sol-gel process, vapour deposition process, microemulsion method and hydro-thermal method, and hydro-thermal method has the advantage that technique is simple, equipment cost is low, but the powder body generated easily is reunited, separate difficulty.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that the synthetic method of a kind of nano yttrium oxide powder.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The synthetic method of a kind of nano yttrium oxide powder, comprises the steps:
(1) in acetic acid yttrium solution, glycerol is first added；
(2) adding sodium hydroxide solution again in the solution of step (1), regulation pH value of solution, to 11-13, then reacts 20-30 hour at 170-200 DEG C；
(3) reacting liquid filtering of step (2), filtering residue is scrubbed, dry, obtain nano yttrium oxide powder after calcining.
Further, the consumption of glycerol is the 1-5% of acetic acid yttrium quality.
Acetic acid yttrium solution concentration is preferably 0.05-0.5mol/L.
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
