Technical Field
The invention relates to the technical field of ceramic sintering, in particular to an ultrafast sintering method and a sintering device for ceramic materials.
Background
Ceramic materials have found wide application in various fields, for example, in the manufacture of solar cells, piezoelectric devices, and the like. The formation of the ceramic material requires that the ceramic powder is changed into a green body through a forming technology, and then the grain of the green body is migrated and grown through a sintering technology, and the green body is shrunk to form the ceramic material. When the ceramic is sintered by the traditional high-temperature sintering method, the sintering temperature is generally over 1000 ℃, and the energy consumption and the cost are higher.
In recent years, a number of new ceramic sintering techniques have emerged. Among them, "Flash Sintering" (Flash Sintering) is a new Sintering process that reduces the Sintering temperature of ceramics with the assistance of electric field and greatly shortens the time required for Sintering. However, the shortening of the sintering time also leads to a new problem that the material shrinkage becomes more rapid and violent, and the two ends of the sample in the flash firing process device in the prior art are clamped by electrodes or stretched by metal wires, which causes great mechanical stress to occur in the material during shrinkage, and the stress can cause the sample to bend and even break, thereby greatly reducing the flash firing yield. In addition, the process of coating conductive paint such as silver paste or platinum paste on the ceramic to form a conductive layer as an electrode is a basic process of flash firing at present, the process not only increases the procedures of coating the electrode and drying, but also after sintering, the ceramic material under the electrode cannot be fully sintered to meet the densification requirement, so that the lower part of the electrode needs to be cut off, and great waste is caused.

Example 1
As shown in fig. 1 and 2, the present embodiment provides an ultrafast sintering apparatus for ceramic materials, comprising:
and a sintering container for accommodating the ceramic green body 1.
Two flexible electrodes 2 are respectively sleeved at two ends of the ceramic green body 1 along the direction perpendicular to the length direction of the ceramic green body 1, and two ends of the flexible electrodes 2 extend out from two ends of the ceramic green body 1.
The lead is connected with two ends of the flexible electrode 2 and can apply outward pulling force to two ends of the flexible electrode 2;

Example 2
The embodiment provides an ultrafast sintering method of ceramic materials, which is implemented by adopting the sintering device in fig. 1, and the power supply 3 adopts a power frequency alternating current power supply 3. The ceramic green compact 1 is prepared by pressing and molding zinc oxide powder with the average grain diameter of 30nm, and the ceramic green compact 1 is in a dog bone shape; fig. 2 shows a method for connecting the ceramic green body 1 and the flexible electrode, in this embodiment, the flexible electrode is made of graphite felt, and the cubic size between the flexible electrodes 2 at two ends of the ceramic green body 1 is 13mm × 3.3mm × 1.7 mm.
Firstly, adjusting the air pressure in a sintering container to 0.02MPa by using a vacuum box; the power supply 3 was turned on and the voltage was gradually increased from zero to 4kV and maintained, after which the current through the ceramic green body 1 was gradually increased over 2min until flash firing occurred, at which time the current through the sample was 600 mA. After the state is maintained for 30s, the voltage returns to zero, the power supply 3 is disconnected, the air pressure is recovered, the ceramic is released from the contact with the flexible electrode 2 after being cooled, and the ceramic is taken out for storage, and the sintering is finished.
The current through the ceramic green body 1 during this firing shows a tendency to change rapidly → slowly rises → when flash firing occurs → remains substantially unchanged; the density, the conductivity, the mechanical property and the like of the ceramic body are in a changing trend of continuously rising to be basically unchanged in the firing process; in the firing process, the ceramic blank 1 is quickly shrunk when flash firing occurs, the graphite felt is always attached to and wraps the ceramic blank, the electrical contact is good, the arc discharge phenomenon is not found, and the ceramic is not bent or broken; the surface temperature of the ceramic body is gradually increased to over 300 ℃ along with the rise of voltage in the sintering process, and is suddenly increased to over 1000 ℃ during flash firing and is basically kept unchanged.

The comparative sintered ceramic was tested using the archimedes drainage method and the calculations showed that the comparative sintered ceramic had a density of 94%.
Comparing the ceramics obtained by sintering in the embodiment 2 and the comparative example, the density of the sintered ceramics in the embodiment 2 is higher than that of the comparative example (adopting a non-flexible electrode), so that the invention overcomes the problem that the two ends of the sample are clamped or stretched in the existing flash firing process to cause the sample to bend or even break due to internal stress when flash firing occurs by introducing the flexible electrode to be electrically connected with the ceramic blank; compared with the prior art, the invention does not need to coat a conductive layer on the ceramic green body to form an electrode, thereby not only reducing the electrode coating and drying procedures, but also avoiding the problem that the ceramic material under the electrode can not be fully sintered to meet the densification requirement. Meanwhile, the method for realizing the flash firing of the ceramic by utilizing the flexible electrode has the advantages of low sintering temperature, low energy consumption, high yield and the like, and still keeps the characteristics of short sintering time, simple device and the like of the flash firing technology.
