Alumina Ceramics

Advanced ceramics

Advanced ceramics are also called industrial ceramics, fine ceramics or high-tech ceramics.

Advanced ceramics have many perfect properties, such as high strength, wear resistance, light weight, high temperature resistance, corrosion resistance, and special properties in many aspects such as sound, electricity, light, heat and magnetism. Therefore, advanced ceramics are widely used in many industries and fields.

Advanced ceramics used as structural materials are mostly developed, such as silicon nitride, silicon carbide, zirconia and alumina ceramics.

Alumina ceramics

Alumina ceramics generally refer to alumina ceramics with alumina content more than 70%.

It is not only a traditional refractory material and wear-resistant material, but also a widely used electronic ceramic material.

Types of alumina ceramics and applications

There are two types of alumina ceramics, high purity alumina ceramics and normal alumina ceramics.

The high-purity alumina ceramics is generally used to replace the platinum crucible, it can also be used as an integrated circuit substrate and high-frequency insulation material in the electronics industry.

Ordinary alumina ceramics are classified into alumina 99, alumina 95, alumina 92, alumina 80 and alumina 75, etc.

99 alumina ceramic material is used to make high temperature crucible, refractory furnace tube and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve sheets;

95 and 92 alumina ceramics are mainly used as corrosion-resistant and wear-resistant ceramic sheets. They are used as ceramic linings for equipment and pipes to improve the service life of equipment;

80 alumina is blended with some talc and other components to improve electrical properties and mechanical strength, and can be used in electronic devices.

Alumina ceramics manufacturing process

Powder preparation

Alumina powder is prepared into a powder material according to different product requirements and different molding processes.

When extrusion or injection molding is used, a binder and a plasticizer are added to the powder.

The powder raw material formed by the hot pressing process does not need to be added with a binder.

In dry pressing, there is a special process requirement for the powder. It is necessary to spray the granulation method to treat the powder to make it spherical, so as to improve the fluidity of the powder and facilitate the automatic filling of the mold during the molding process.

Forming

Alumina ceramic products forming methods include dry pressing, grouting, extrusion, cold isostatic pressing, hot isostatic pressing, injection, casting, hot die casting, and the like.

Sintering

The technical method of densifying a granular ceramic body and forming a solid material is called sintering. Sintering is to remove the voids between the particles in the body, remove a small amount of gas and impurity organic matter, and make the particles grow and combine with each other to form a new substance.

The heating device for alumina precision ceramic parts is most widely used in electric furnaces. The firing of alumina wear-resistant ceramic tiles and alumina grinding media will use tunnel kiln.
