Introduction to the sintering method of alumina ceramic parts

With the continuous development and progress of science and technology, alumina ceramic parts with superior performance have been widely used in various fields, then Pintejin Ceramics will introduce the sintering method of alumina ceramic parts to you.

Sintering method of alumina ceramic parts

1. Activated hot pressing sintering

Activation sintering is a relatively traditional sintering method, and activation hot pressing sintering is a new process developed on this basis.If alumina ceramic manufacturers use this method to sinter alumina ceramic parts, the reactants will have a relatively high energy activation state when a decomposition reaction or phase transition occurs.At this time, hot pressing can be used to obtain high-density alumina ceramic parts. This process requires short time, low pressure and low temperature, so the sintering efficiency is high.

2. Ultra-high pressure sintering

If the ultra-high pressure sintering method is used to sinter alumina ceramic parts, the alumina ceramic manufacturer needs to sinter at a pressure above hundreds of thousands of atmospheres.Sintering in this way not only allows the material to quickly reach a high density, but also has fine grains less than one micron and changes the electronic state of the crystal structure, so that the manufactured alumina ceramic parts have the advantages of conventional sintering. possessed performance.

3. Electric field sintering

Alumina ceramics manufacturers can also use the electric field sintering method. During sintering, the ceramic body can be sintered under the action of a DC electric field, so that certain components in the material can be removed.A direct current field can be applied to both ends of the green body at the sintering temperature, and then the electric field can be removed after cooling to a certain temperature to obtain an alumina ceramic part with piezoelectricity.The above is the sintering method of alumina ceramic parts brought to you by Pintejin Ceramics.
