In fact, there are many aspects of the sintering method of alumina ceramic roller. The first thing we must introduce is the activation hot-press sintering of alumina ceramic roller. In fact, it is also a new process that is directly developed on the basis of activation sintering. In addition, we must pay attention to the fact that it is actually the heat treatment performed by the reactants during the decomposition reaction or the phase transition.

For the sintering of alumina ceramic roller, it can be directly at a lower temperature or a smaller pressure, and there is a material that can obtain high-density ceramics 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 roller. In fact, it is sintering under ultra-high pressure sintering, that is, under a pressure of hundreds of thousands of atmospheres. For its characteristics, it can not only directly achieve a high density of materials, but in fact, it will directly have a fine grain.

For the ultra-high pressure sintering of alumina ceramic roller, it can make the electronic state of the crystal structure even make a series of changes in its atoms. In this way, it can also directly give the material a general sintering or a hot press sintering process. At the time, a performance that could not be achieved. And, in fact, it is also a direct synthesis of a new type of artificial minerals. However, for its ultra-high pressure sintering process, it is actually quite complicated.

Finally, we briefly introduce the electric field sintering of alumina ceramic roller. That is, the ceramic body is sintered under the action of our DC electric field, and the DC tune field is applied to both ends of a ferroelectric ceramic at some high Curie point inside the alumina ceramic rod, 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.
