Abstract

The invention discloses a preparation method of Y2O3 superfine powder by virtue of PEG4000 and SDBS compound precipitation. The method comprises the following steps: adding crude yttrium oxide powder into a hot concentrated nitric acid solution and diluting the solution to obtain a Y(NO3)3 solution; adding compounding dispersants PEG4000 and SDBS; dispersing uniformly in an ultrasonic manner; titrating the Y(NO3)3 solution by a diluted ammonia water solution; centrifugally separating an obtained precursor precipitate; respectively filtering and washing by using deionized water and absolute ethanol; and drying the filtered precursor in a drying box at the temperature of 80 DEG C for 2 hours, and then baking in a programmable temperature control electric furnace at the temperature of 750 DEG C for 3 hours to obtain the superfine Y2O3 powder. The preparation method disclosed by the invention has the beneficial effects of low production cost and short reaction period and is simple to operate, and large-scale continuous industrial production is easier to carry out.

Description

Y 2o 3the composite precipitation method of PEG4000-SDBS of superfine powder
Technical field
The present invention relates to Y 2o 3the composite precipitation method of PEG4000-SDBS of superfine powder.
Background technology
Y 2o 3superfine powder, because of himself special physicochemical property and excellent optical property, has been widely used in the middle of numerous areas.Wherein the yttrium oxide powder of nanoscale is many because its larger specific surface area shows plants excellent performance, along with research work further deeply, its potential using value and the new Application Areas of Geng Duo will be excavated out.
About the preparation method of superfine oxide, recent domestic expands to be studied widely, be summed up and mainly comprise solid phase method, vapor phase process, liquid phase method etc., wherein liquid phase method comprises again sol-gel method (sol-gel), hydrothermal synthesis method, spray pyrolysis, the precipitator method etc.Can synthesize in the method for yttrium oxide superfine powder all at present, select more or in liquid phase method the precipitator method, and direct precipitation method is wherein adopt maximum preparation methods at present because its technique simple possible, cost ineffective rate are high, be easy to suitability for industrialized production, and other liquid phase method because of physical condition that its high cost, risk factor are high and harsh can only be too much be confined to laboratory study, the stage of moving towards the industrialization is also immature.Y is prepared at traditional liquid-phase precipitation method 2o 3in superfine powder, usually adopt water to be reaction medium, the hydrogen bond that the planar water on deposit seeds surface is formed is the root that powder hard aggregation produces, thus causes the generation of hard aggregation to be inevitable.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, provides Y 2o 3the composite precipitation method of PEG4000-SDBS of superfine powder.
To achieve these goals, technical scheme provided by the invention is: Y 2o 3the composite precipitation method of PEG4000-SDBS of superfine powder, comprises the following steps: slowly joined by meal yttrium oxide in the concentrated nitric acid solution constantly stirring and heat, dilute the Y (NO that previous gained solution obtains desired concn 3) 3solution, adds composite dispersion agent PEG4000 and SDBS, and ultrasonic disperse is even, joins Y (NO with the ammonia soln titration after dilution 3) 3solution, under the situation of magnetic force rapid stirring, slow dropping, drip speed control built in 2ml/min, be separated under the presoma throw out high speed centrifugation obtained, then use deionized water and dehydrated alcohol filtering and washing respectively, the presoma after suction filtration is put into baking oven at 80 DEG C of dry 2h, then temperature programmed control electric furnace 750 DEG C of roasting 3h are put into, obtained Y 2o 3superfine powder.
Beneficial effect of the present invention is: Y provided by the invention 2o 3the composite precipitation method of PEG4000-SDBS of superfine powder, production cost is low, simple to operate, reaction time short being easier to carry out large-scale continuity suitability for industrialized production.Overcome the existence of presoma throw out surface adsorption water and the product particle hard aggregation phenomenon caused, yttrium oxide superfine powder size distribution relative narrower, disperse relatively uniform.
