Abstract
A method for synthesizing a lanthanum molybdate-based electrolyte material by a microwave combustion-supporting method in one step relates to the technical field of preparation of lanthanum molybdate-based electrolyte materials. The chemical formula of the lanthanum molybdate based electrolyte material is La2‑ xAxMo2‑yByO9‑Lanthanum nitrate, salt of corresponding elements of A/B, ammonium molybdate and a complexing agent are used as reaction raw materials, sol is formed by heating and evaporation, a nanoscale precursor is formed by spraying through a spraying machine, the nanoscale precursor is placed in a microwave oven for microwave heating and combustion to obtain nano powder, and finally tabletting and sintering are carried out to obtain the nano powder. The invention combines the microwave method and the self-combustion method, and the wave radiation energy enables the interior of the reaction system to be heated uniformly and rapidly when the microwave is used for heating and supporting combustion, thereby being capable of rapidly and comprehensively exciting the combustion reaction.

Technical field
The present invention relates to lanthanum molybdate-based electrolyte preparing technical field, a kind of combustion-supporting step of method one of microwave is specifically related to
The method for synthesizing lanthanum molybdate-based electrolyte.
Background technology
It is well known that SOFC is a kind of new and effective, clean TRT that chemical energy is converted into electric energy, heat
The energy conversion efficiency of Electricity Federation production is up to more than 80%, is described as the novel green chemical energy source of 21 century.The one of current SOFC
Individual study hotspot is to reduce SOFC operating temperature, is enabled in middle temperature even low operating temperatures.In having been studied
Warm electrolyte has lanthanum gallate, cerium oxide, lanthanum molybdate etc..Lanthanum molybdate is that Laccore was reported first in 2000, its
600~800 DEG C of mesophilic range electrical conductivity is higher than traditional electrolyte matter YSZ, in addition lanthanum molybdate-based oxidesolid electrolyte material
Sintering temperature it is low, the price of raw material is relatively low, therefore lanthanum molybdate is used as the oxidesolid electrolyte material of intermediate temperature SOFC
Candidate material has much competitiveness.
The synthesis of current lanthanum molybdate-based electrolyte mainly has solid reaction process and sol-gal process.Sol-gal process,
The method is typically that the salt of the element containing target product is stoichiometrically hybridly prepared into the aqueous solution, adds a certain amount of complexing
Gel presoma, thermally treated removing organic remains is made in agent, slow evaporation, then calcining can obtain required production at high temperature
Thing.The method needs the high temperature lower long period to be heat-treated and calcine, and easily causes and further reunites between powder.Solid reaction process passes through
Machinery is by raw material mixed grinding, then obtains the target product technical schemes through high-temperature roasting and have the disadvantage to reach the uniform mixed of raw material
Close more difficult, the uniformity of powder constituents is difficult to be guaranteed, and particle size fineness and the uniformity are poor, need further to be carried
It is high.Meanwhile, solid phase method and the shortcomings of sol-gal process also has production cycle length, cost is high.
In addition, researcher is also studied other synthetic methods, including freeze-drying, Via Polymeric Precursor Method,
Hydro-thermal method, situ aggregation method etc., achieve certain achievement, but there is complicated experimentation, synthesis condition harshness, single
Products therefrom is less, the problems such as be not suitable for being prepared on a large scale.
The content of the invention
For the above-mentioned technical problem that presently, there are, the invention provides a kind of combustion-supporting method one-step synthesis of microwave is lanthanum molybdate-based
The method of electrolyte, heats spontaneous combustion, the advantage of spray shaping three is combined, it reacts by sol-gal process, microwave
Time is short, and technological process is simple, even particle size distribution and cost is relatively low.
To achieve these goals, the technical solution adopted in the present invention is：A kind of lanthanum molybdate-based electrolyte, chemistry
Formula is La2-xAxMo2-yByO9-δ, A is Sm, Dy, Pr, Gd, Y, Nd, Ba, Sr, Ca in formula；B is W, Al, Mn, Bi, Cr, Fe；X values are
0~0.7, y value are 0~1.
A kind of method of the combustion-supporting lanthanum molybdate-based electrolyte of method one-step synthesis of microwave, with lanthanum nitrate, A/B corresponding elements
Salt, ammonium molybdate and complexing agent are reaction raw materials, and heating evaporation formation colloidal sol sprays to form nanoscale presoma by spraying machine,
Microwave heating burning in micro-wave oven being placed on again nano-powder being made, last tabletting, sintering are made.
As the preferred technical solution of the present invention, preparation method step is as follows：
1), according to La2-xAxMo2-yByO9-δThe chemical dosage ratio of chemical formula is by lanthanum nitrate, the salt and molybdic acid of A/B corresponding elements
Ammonium is dissolved in distilled water, stirs into mixed solution；
2) complexing agent, is added into mixed solution, be heated to 60~90 DEG C stirring evaporation solvents using formed mass concentration as
15~40% colloidal sol；
3), spray to form La using spraying machine2-xAxMo2-yByO9-δNanoscale presoma；
4) presoma, is placed in microwave heating burning in micro-wave oven La is made2-xAxMo2-yByO9-δNano-powder；
5) it is, that gained powder is dry-pressing formed, the disk after shaping is incubated 5~10h at 800~1100 DEG C and sintered into
Porcelain.
As present invention further optimization technical scheme, in preparation method, step 1) in gold in the mixed solution prepared
It is 0.1~4mol/L to belong to the total molar concentration of ion.Complexing agent be citric acid or glycine or polyacrylamide, complexing agent plus
Enter 1~2.2 times that amount is metal ion mole total amount in mixed solution.
Compared with prior art, the present invention has advantages below：
1), spray to form La using spraying machine2-xAxMo2-yByO9-δNanoscale presoma, is " micro- using nanoscale presoma
Reaction interval ", can make the processes such as nucleation, growth, coalescence, reunion be confined to a small spherical interval interior progress, it is to avoid
Further reunite between particle, so as to reach control particle size, the purpose of shape.
2), microwave method is combined with auto-combustion method, microwave heating it is combustion-supporting when wave radiation energy make inside reaction system by
It is hot uniform rapid, combustion reaction can be quickly excited comprehensively.Presoma uniformly quickly produces combustion reaction, and temperature height can be closed with a step
Into powder, the yield of unit interval is high, it is to avoid the high-temperature burning process in commonsense method later stage.
3), combustion process is maintained by self-heat generation, it is no longer necessary to which the external world provides energy.And it is common micro- except exciting burning to need
Ripple stove is provided outside few heat, and expensive high temperature furnace is not needed in material synthesis processes.
4), using sol-gel technique, generation material atom level can be made uniform.
