|Introduction of zirconia ceramic articles have a lot of, but this way but there are a lot of differences. Below we will from many fields to introduce the application of zirconia ceramics and its production process. I hope I can bring you different feeling, also hope to bring you. Specific content as follows, for reference only.|
In terms of structural ceramics, because zirconia ceramic with high toughness, high bending strength and high wear resistance, good insulation properties, thermal expansion coefficient to steel etc, and therefore is widely applied in the field of structural ceramics.
In terms of functional ceramics, its excellent high temperature resistant performance as induction heating pipe, refractory material, heating elements. Zirconia ceramics has sensitive electrical parameters, mainly used in oxygen sensors, high temperature solid oxide fuel cell and heating element etc.
Zirconia ceramics production requirements of the preparation of high purity, good dispersion performance and ultrafine particles, narrow particle size distribution of the powder, zirconium oxide superfine powder preparation method are many, the purification of zirconia mainly include chlorination and thermal decomposition method, alkali metal oxide decomposition method, lime melting method, plasma arc method, precipitation, colloid, hydrolysis, spray pyrolysis method, etc. Powder processing methods have a total precipitation, sol gel method, evaporation method, supercritical synthesis method and microemulsion method, hydrothermal synthesis law and vapor deposition method, etc.
Zirconia ceramic forming a dry pressing molding, such as static pressure molding, injection molding, die-casting molding, heat flow delay processing, injection molding, plastic extrusion molding, colloidal solidified, etc. (figure/ http://www.jiangsuceramics.com/)
