Introduction to Zirconia Ceramic Buttons

Zirconia ceramic buttons, that is, buttons polished by using the characteristics of zirconia and ceramic powder, have good heat resistance, high hardness, environmental protection and pressure resistance.
Zirconia ceramic buttons have high strength and toughness at room temperature, good wear resistance, high temperature corrosion resistance, high hardness and high brightness. At 1000 ℃, the strength and hardness of zirconia ceramic balls are almost unchanged, and the density is 8.00g/cm3, while at room temperature, it can remain unchanged for a long time.
Zirconia ceramic buttons, that is, its production requires the preparation of powders with high purity, good dispersion performance, ultra-fine particles and narrow particle size distribution. There are many preparation methods for zirconia ultra-fine powder. The purification of zirconia mainly includes chlorination and thermal decomposition. method, alkali metal oxidation decomposition method, lime melting method, plasma arc method, precipitation method, colloid method, hydrolysis method, spray pyrolysis method, etc. Powder processing methods include co-precipitation method, sol-gel method, evaporation method, supercritical synthesis method, microemulsion method, hydrothermal synthesis method, network and vapor deposition method.

In the mixed material selection, it needs to be mixed in a ratio of 1 to 5, calcined at a high temperature of 2000 ° C to form embryos, cooled and preliminarily polished, returned to the furnace to continue calcined and formed, and then integrated with other processes.
