Abstract
The invention relates to a preparation method of metallurgy material, in particular to a preparation method of ultrafine zirconia. The preparation method of ultrafine zirconia is completed by utilizing the low-temperature combustion and promoting agent addition method. Compared with the conventional preparation method, the preparation method of ultrafine zirconia has the characteristics of safety, no pollution, simple preparation process without overhigh temperature condition and high purity quotient of the prepared product.
Description
One, technical field:
The present invention relates to the preparation method's of metallurgical material, particularly a kind of superfine zirconia preparation method.
Two, background technology:
Preparation method for superfine powder generally is divided into physics method and chemical method at present, and wherein, the physics method comprises mechanical mill, solid phase method etc.; Chemical method comprises wet chemistry method, solvent evaporated method etc.Mainly contain solid phase method, chemical gas-phase method, the precipitator method, metal alkoxide method etc. for the method for preparing superfine zirconia both at home and abroad.Aforesaid method all has the reaction process complexity, easily produces impurity, and needs very high temperature condition, metal alkoxide method particularly, in the process of preparation, need a large amount of expensive organometallic compounds, and often be some deleterious materials, easily environment is produced and pollute as the organism of solvent.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, a kind of preparation method of superfine zirconia is provided.It is simple that this method has preparation process, do not need too high temperature condition, and safety non-pollution, the characteristics that the product purity of preparing is high.
The technical scheme that the present invention is adopted for achieving the above object is: the preparation method of superfine zirconia, the nitric hydrate salt loading aqueous solution and organic-fuel heating as oxygenant are made its catching fire, add promoting agent then, low-temperature burning to granulated powders is separated out, and obtains the loose oxide compound superfine powder of spumescence.
The described organic-fuel of selecting for use is a urea.
The preparation method of the promoting agent of described adding is: formed according to volume ratio 1:2:2:1 mixed by tensio-active agent, oil, water, cosurfactant.
Characteristics of the present invention: the present invention utilizes the method for low-temperature burning and interpolation promoting agent to finish the preparation process of superfine zirconia, compare with preparation method in the past, present method has safety non-pollution, preparation process is simple, do not need too high temperature condition, and the high characteristics of the product purity of preparing.
Four, embodiment:
Below in conjunction with embodiment the present invention is described in further detail, but is not limited to specific embodiment.
The preparation method's of superfine zirconia concrete implementation step is:
1, the configuration nitric hydrate salt loading aqueous solution is got organic-fuel urea ready.
2, preparation promoting agent, the preparation method is: formed according to volume ratio 1:2:2:1 mixed by tensio-active agent, oil, water, cosurfactant.
3, the nitric hydrate salt loading aqueous solution and organic-fuel heating as oxygenant are made its catching fire.
4, add promoting agent, low-temperature burning to granulated powders is separated out, and obtains the loose oxide compound superfine powder of spumescence.
Claims (3)
