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 a kind of method improving meat-type duck seedling percent.
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 yttrium nitrate solution, mannitol 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 mannitol is the 1-5% of Yttrium trinitrate quality.
Yttrium nitrate solution concentration is preferably 0.05-0.5mol/L.
