Introduction of preparation technology of zirconia ceramic powder

The extremely hard zirconia ceramic rods, ceramic tubes, ceramic parts, etc. are all made of fine zirconia ceramic powder through layer-by-layer process, so how is the powder made? The following Kezhong Ceramics Factory will give you a brief introduction.

Zirconia ceramic powder can not be obtained by simple grinding, but can only be prepared through a series of operations.

On the whole, zirconia ceramic powder needs to undergo raw material pretreatment, neutralization and coprecipitation, washing and filter pressing, primary stabilization, grinding equalization, secondary stabilization, crushing and other processes before it can be perfectly formed. Pretreatment is to prepare the required raw materials according to a certain proportion, and heat, stir and vacuum filter them for later use.

Pour pure water into the treated raw materials and stir, at the same time, add a certain amount of prepared dilute ammonia water and organic dispersant, and stir until the solution is completely neutralized to obtain coprecipitate. Then a dispersant is added to wash the coprecipitate, and then a filter press operation is carried out, and finally a filter cake meeting the requirements is obtained. If the filter cake is stabilized after heat treatment, it can be crushed, but the obtained material can not meet the needs, and it needs secondary stabilization and crushing, and the final product is zirconia ceramic powder.
