Description

A kind of oxygen ion conductor material and preparation method of alumino-silicate melilite structure
Technical field
The present invention relates to oxygen ion conductor material, more particularly to can be applied to the electricity based on oxygen ion conduction elastomeric material The oxonium ion of the devices such as chemical device such as solid-oxide fuel battery electrolyte, lambda sensor, oxygen ion pump, oxygen separation membrane Conductor material and preparation method thereof.
Background technique
Oxygen ion conductor is including solid oxide fuel cell (SOFC), oxonium ion sensor, oxygen ion pump, oxygen point From being widely used in important technologies such as natural gas oxidations in film and synthesis gas production.In order to reduce the work of these devices Temperature, people taste the research for trying to find novel oxygen ion conductor and they being carried out with atom level transmission mechanism.Traditional oxygen Ionic conductor material be usually oxygen ion conduction is realized by the conduction of anion vacancy, such as high symmetry fluorite and Perovskite structure.However nearest research has revealed that out, it is real using excessive gaps oxonium ion as the material system of carrying object Having showed has higher oxygen ionic conductivity relative to vacancy type conductive material, these material structure types include stratiform calcium titanium Mine,, apatite, scheelite, the materials such as mayenite and melilite.
Currently, the melilite type gap oxygen ion conductor being reported is only gallate, and more have cost-benefit Whether no gallium compound, which is capable of providing gap oxide ion conduction, but has not been reported.
Summary of the invention
That the object of the present invention is to provide a kind of chemical stabilities is good, mechanical performance is excellent, low in cost, while having high Oxygen ion conductor material of oxygen ionic conductivity and preparation method thereof.
The chemical composition of oxygen ion conductor material of the invention is La3Sr3MgSi2Al6O21.5。
The preparation method step of the oxygen ion conductor material are as follows:
It (1) is La more than 99.9% (mass percent) by purity2O3、SrCO3、 MgO、SiO2And Al2O3Starting powder is pressed According to La3Sr3MgSi2Al6O21.5Metering than composition weigh ingredient；
(2) by step (1) raw material wet ball-milling 15 hours, ball-milling medium is dehydrated alcohol, is dried after ball milling in 80 DEG C；
(3) powder after drying is heated to melting in 2210 ~ 2250 DEG C of air atmospheres, then quenching obtains glassy state Presoma；
(4) glassy state presoma made from step (3) is annealed 4 ~ 8 hours at 800 DEG C, glass is made to be fully crystallized to obtain mesh Mark the ceramic material of works phase.
Material particle size prepared by the present invention is small, and mechanical performance is excellent, and chemical stability is good；Oxygen ionic conductivity exists 2.2 × 10 are up at 600 DEG C−2 ~ 2.5×10−2S/cm can be widely applied to various electrochemical devices, such as soild oxide Fuel-cell electrolyte, lambda sensor, oxygen ion pump, oxygen separation membrane and synthesis gas production in natural gas oxidation etc., especially It is the technical requirements that can meet low-temperature solid oxide fuel cell electrolyte, industrially great application prospect.
Specific embodiment
Embodiment:
Table 1 show constitute glassy state presoma of the invention at 800 DEG C 3 specific embodiments of different annealing times and Its oxygen ionic conductivity at 600 DEG C.Its preparation method is as described above, using Impedance Method to oxygen-ion conduction Rate is tested.
Oxygen ion conductor material of the present invention can be widely applied to the various electrochemical devices based on oxygen ion conduction, especially It is the great application prospect in low-temperature solid oxide fuel cell.
