Brief Introduction：
The sintering method of alumina ceramics actually has many aspects. The first thing to be introduced is an activation hot press sintering. On the basis of stopping activation and sintering, a new process has been stopped directly. Furthermore, we should note that it is a heat treatment that uses the reaction to stop the synthesis reaction or the phase change.
The sintering of alumina ceramics can be directly at a lower temperature or a lower pressure, and it is also a material for obtaining high-density ceramics in a relatively short time. In general, it is actually a kind of high efficiency A hot pressing technique.
The ultra-high pressure sintering of alumina ceramics is sintered at a pressure of more than hundreds of thousands of atmospheres, which can directly make the material quickly reach high density, and in this way, it will directly have fine grains. It can make a series of changes in the electronic state of the crystal structure and even its atoms. In this way, it can directly endow the material with a performance that cannot be achieved in the usual sintering or hot-pressing sintering process. Moreover, the ultra-high pressure sintering of alumina ceramics can directly synthesize a new type of artificial mineral.
There is also the electric field sintering of alumina ceramics. The ceramic body is sintered under the action of a direct current electric field. A direct current field is applied to the two ends of a ferroelectric ceramic at some high Curie points in the alumina ceramic, and wait until it is cooled to When our Curie point is below 1210℃, remove the electric field, so that a ceramic sample with piezoelectricity can be obtained.
