What is the finishing process of alumina ceramics?

alumina ceramic

It is not uncommon for alumina ceramic materials on the market now. This material is suitable for the chemical properties of alumina, but not the combination of alumina and ceramics. This alumina ceramic material is the same as other different materials, thermal conductivity, and ductility. Both have great advantages.

So what is the finishing process of alumina ceramics? Alumina finishing processes and what are they?

Alumina is also the scientific name of chemical alumina (Al2O3), and the chemical composition of ceramics is generally silicon dioxide (SiO2) and calcium carbonate (CaCO3). The finishing process of alumina ceramics is the preparation of powder. This preparation method has a high forming rate, fast work efficiency, and high product success rate.

The alumina ceramic finishing process is to first put the alumina powder into the factory, and prepare it into powdery materials by different molding processes according to different product requirements.

The particle size of this powder is required to be less than 1 μm. If high-purity alumina ceramic products are manufactured, in addition to the purity of alumina reaching 99.99%, the ultra-fine powder is also required to obtain a uniform particle size distribution of the ultra-fine powder.

Then the ultrafine powder will be kneaded powder or injection molding method. During the preparation process, the powder needs to introduce a binder and plasticizer. It should be noted that the binder and plasticizer have a certain share requirement. The general situation is 10-30% by weight of thermoplastics or resins. The organic binder should be uniformly mixed with the alumina powder at 150-200 degrees Celsius to facilitate the molding operation.
