Zirconia ZrO2 Ceramic

Zirconia ZrO2 Ceramic is one typical technical ceramic with high hardness and good fracture toughness. ZrO2 ceramic has excellent self-lubricating properties, which can effectively solve the pollution caused by lubricating substances and the trouble of adding inconvenience. Zirconium Oxide Zirconia ceramics need high-purity oxidation ZrO2 powder with good particle size dispersion of zirconium particles. As an oxide ceramic material, the ceramic prepared by ZrO2 powder is usually white, and under some specific sintering environment, the ceramic will appear light yellow.

More Information

Among the machining process methods of zirconia based ceramic, the mechanical machining methods are highly efficient, so they are widely used in industry, especially diamond wheel grinding and polishing are more common. Although there are many methods for machining zirconia ceramics, the machining cost is high, the processing efficiency is low, and the processing accuracy is poor. One of the main reasons is that the hardness of technical ceramics is extremely high. For the Zr02 ceramic unsintered or calcined body, the rough machining is mainly carried out by cutting, and after sintering (the process of transforming the powdery material into a highly densed body), it is finished by grinding. According to the different conditions of zirconia ceramics, the sintered body can be directly ground without processing to achieve the design accuracy (precision).
