alumina ceramic

In fact, the alumina ceramic normal pressure sintering method is the entire process of sintering the green body under atmospheric conditions. This method will have a higher sintering temperature, so the requirements for the kiln are higher, and energy is wasted. It is also very large.

1. Sintering method of alumina ceramics by hot pressing:

The sintering method of alumina ceramics by hot pressing is lower in temperature than normal temperature sintering, and the theoretical density can be 99% after sintering. Because hot pressing sintering mainly uses preforming, Loading the powder directly into the mold is relatively simple.

2. Sintering method of alumina ceramic electric field:

Rhenium is the direct sintering of the alumina ceramic body to complete the entire sintering process.

3. Sintering method of ultra-high pressure alumina ceramics:

Rhenium requires alumina ceramics to perform the entire work of sintering under a pressure of several hundred thousand atmospheres or more.

4. Sintering method of alumina ceramic atmosphere:

Rhenium is mainly for alumina ceramic which is more difficult to sinter in air. In order to prevent oxidation, it is possible to enter the appropriate gas in the furnace to form the required atmosphere effect. Sintering is completed in this atmosphere.
