Seeing the sintering method of alumina ceramic roller actually has a lot of aspects, we must stop the introduction actually is activated hot pressing sintering of alumina ceramic roller. In fact, it is a new process that ceases direct development and ceases to activate the sintering process. Furthermore, we must stop paying attention, which is actually the application of reverberations to stop the synthesizing repercussions or the thermal disposition of phase-change suspension.

Regarding the sintering of alumina ceramic rollers, it is actually able to directly be at a lower temperature or a smaller pressure, and there is a material for obtaining a high-density ceramic in a relatively short period of time. In general, it is In fact, it is a hot-press technology with high efficiency.

The next step is ultra high-pressure sintering of alumina ceramic rollers. In fact, it is to stop the sintering under ultra-high pressure sintering, that is, a pressure of hundreds of thousands of atmospheres. As far as its characteristics are concerned, it can not only make the data reach the high density quickly, but in fact, it will directly have a fine grain.

Regarding the ultra-high-pressure sintering of alumina ceramic rollers, it can make the crystal structure electron state so that its atoms can make a series of changes. In this case, it can directly assign data to the general sintering or hot press sintering process. At the time, one performance that cannot be achieved. And, in fact, it is also able to directly synthesize a new type of artificial minerals. However, in terms of its ultra-high pressure sintering process, it is actually more complex.

Let us briefly introduce the electric field sintering of alumina ceramic rollers. That is, the ceramic body stops sintering under the action of our DC electric field, and applies a direct current field at both ends of a ferroelectric ceramic at some high Curie point inside the alumina ceramic roller, until it cools down to our residence. When the temperature is below 1210°C, we also need to remove the electric field so that a ceramic sample with piezoelectricity can be obtained.
