1067 DEG C) etc. particles generally in tens microns, with so coarse particle can not by the granular precursor of nanoscale every
From.And the methods of passing through ball milling, is also difficult to the size reduction of salt particle to Nano grade.
Reunite in conclusion metal oxide nanoparticles are difficult to avoid that in preparation process in high-temperature calcination decomposable process
And sintering, and the prior art is difficult to solve the problems, such as this.Using high-melting-point water-soluble inorganic salt come be isolated granular precursor be solve
One possible approaches of this problem, but on condition that the tiny water soluble salt particle of particle must be prepared, and use water soluble salt
Presoma is effectively disperseed and is isolated by particle, can avoid reunion of the metal oxide nanoparticles in high-temperature burning process and
Sintering Problem prepares the metal oxide nanoparticles of polymolecularity.

It uses.The present invention prepares the granular potassium sulfate of nano-scale, and has carried out surface modification to nanometer granular potassium sulfate, makes it
Grain uniformly disperses in dimethylbenzene.
Advantageous effect：Compared with prior art, the present invention it has the following advantages：
The existing method for preparing nano-metal-oxide, such as chemical precipitation method, sol-gal process, usually make first
For presoma, such as metal carbonate or hydroxide is gone out, then calcine at high temperature, resolve into metal oxide.But particle
Size is smaller, and surface can be bigger, easier reunion.Either in dehydration and drying process still in high-temperature burning process, metal

The mechanism of action of polyacrylic acid it is not immediately clear, nucleating agent is also not present in organic solvent precipitation method technical field
Concept.In metal freezing field, nucleating agent is solid particle, forming core substrate when can be as metal freezing, so as to significantly
It improves nucleation rate, reduce crystallite dimension.And polyacrylic acid is dissolved in the high molecular material of water, the mechanism of action in process of setting
Solid nucleating agent obviously have a very big difference, therefore polyacrylic acid promote the effect of potassium sulfate forming core be those skilled in the art without
Method precognition.
When the aqueous solution of salt is added in weakly polar organic solvent miscible with water, solubility declines to a great extent, salt
Grain will be precipitated from organic solvent, but the crystal being usually precipitated is micron order.Sulphur can be promoted using polyacrylic acid in the present invention
The forming core of sour potassium is added in organic solvent in the potassium sulfate solution containing polyacrylic acid, and the nucleation rate of potassium sulfate is significantly
It improves, and therefore greatly reduces particle size.Add in more than 0.5% potassium sulfate quality polyacrylic acid when, can effectively by
The size reduction of granular potassium sulfate is to 100nm hereinafter, as shown in Figure of description 1.
The mechanism of action of polyacrylic acid it is not immediately clear, nucleating agent is also not present in organic solvent precipitation method technical field
Concept.In metal freezing field, nucleating agent is solid particle, forming core substrate when can be as metal freezing, so as to significantly
It improves nucleation rate, reduce crystallite dimension.And polyacrylic acid is dissolved in the high molecular material of water, the mechanism of action in process of setting
Solid nucleating agent obviously have very big difference.It is according to the prior art that polyacrylic acid, which promotes the effect of potassium sulfate forming core, in the present invention
Knowledge is unpredictable.
The nanometer potassium sulfate of the present invention is particularly suitable for mutually being used to prepare nano-metal-oxide as isolation.But we will
Nanometer potassium sulfate and presoma nano particle in ethyl alcohol when being stirred mixing in organic solvents, find nanometer granular potassium sulfate
Still in aggregating state, it is unable to reach the purpose of dispersion granular precursor.The present invention uses nanometer potassium sulfate in ethanol in advance
Stearic acid carries out surface modification, can make nano-sulfur acid potassium fine dispersion in dimethylbenzene, and obtain transparent dispersion liquid.At this time plus
Enter metal oxide precursor, the nanometer potassium sulfate after dispersion, which can serve as isolation, mutually to be disperseed granular precursor and be isolated.
High-temperature calcination will be carried out after granular precursor after dispersion and the centrifugation of nanometer potassium sulfate, drying, presoma decomposes life
Into nano-metal-oxide, and nanometer potassium sulfate does not decompose.In the generating process of nano-metal-oxide, always by nano-sulfur
Sour potassium solid particle dispersions are simultaneously isolated, therefore will not reunite and be sintered, and can obtain dispersion after washing removal potassium sulfate receives
Rice metal oxide.If to calcined product secondary clacining in a reducing atmosphere, the Nano metal powder that can must disperse after washing.
If adding in surfactant in dimethylbenzene dispersion liquid, it will further improve the isolation effect of nanometer potassium sulfate
Fruit.It is even that surfactant includes polyethylene glycol, polyvinylpyrrolidone, carboxylic acids surfactant, silane coupling agent, Aluminate
Join agent etc..
The present invention can prepare the nano-metal-oxide of favorable dispersibility with rapid batch, solve nano-metal-oxide
Reunion and Sintering Problem, and since calcination temperature is up to 1000 DEG C, prepared nano-metal-oxide crystallinity
Well.Similarly, the Nano metal powder that prepared by the present invention crystallizes perfect, electric conductivity and magnetic property is good.
In addition, the present invention can not only prepare single metal oxide nanoparticles, it can be with expanded application in preparation
Composite oxides, such as yttrium aluminate, magnesium aluminate spinel and nickel ferrite based magnetic loaded complex oxide.
Preparation method of the present invention is easy, is easy to mass produce.
