Now on the market, alumina ceramic material is not rare, this material applied to the chemical properties of alumina, but not the combination of alumina and ceramic, this alumina ceramic material with other different materials of the same pass, thermal conductivity and ductility have a great advantage.

So what is the finishing process of alumina ceramics? Alumina finishing process and what are they?
Alumina is also the chemical alumina (Al2O3) scientific name, and the chemical composition of ceramics are 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 molding rate, fast working efficiency, and high product success rate.

Alumina ceramic finishing process is the first alumina powder into the plant in accordance with the different product requirements to different molding process preparation into powder materials.

This powder particle size requirements in 1μm or less, if the manufacture of high-purity alumina ceramic products, then in addition to alumina purity to 99.99%, but also the need to ultra-fine powder and make the powder has been ultra-fine powder particle size dispersion uniform.

Then the ultra-fine powder will be used to knead the powder or injection molding method, in the preparation process, the powder needs to introduce binder and plasticizer, need to pay attention to is that the binder and plasticizer has a certain share of requirements, the general situation for the weight ratio in 10-30% of the thermoplastic plastic or resin. Organic binder should be mixed evenly with alumina powder at 150-200 degrees Celsius to facilitate the molding operation.
