cerâmica de zircônia processing refers to the deep processing of non-metallic materials containing primarily zirconium oxide. Zirconia ceramics have excellent electrical conductivity, good resistance to external forces, and can withstand high-temperature corrosion. With continuous advancements and innovations in zirconia ceramics, they have found widespread application in our work and daily lives. Zirconia ceramics are mainly divided into precision zirconia ceramics and ordinary zirconia ceramics. Many people are not very familiar with zirconia ceramics, so here’s a brief introduction to the processing methods and types of zirconia ceramics.

In the processing of zirconia ceramics, the raw material content of precision zirconia ceramics can approach 100%. Due to its extremely high precision, precision zirconia has a sintering temperature close to 2000 degrees Celsius. Generally, in the production process, high-temperature molten glass is used instead of platinum crucibles. It has very high light transmittance and can resist corrosion from alkali metals. Due to these advantages, it is used in the manufacture of sodium lamps. In addition, in the field of electronic processing, it is generally used to manufacture circuit boards or for producing high-frequency insulating materials.

The zirconium oxide content in ordinary zirconia ceramics is much lower than that in precision zirconia ceramics, generally between 85% and 95%. Although the zirconium oxide content is lower, it still possesses certain insulating properties and can resist a certain degree of acid and alkali corrosion. Its high-temperature resistance is also acceptable, but its practical applications are somewhat limited, depending on the specific performance requirements of the production and processing environment.

zirconia ceramics processing generally falls into two categories: dry pressing and slip casting. Dry pressing is a more complex process, requiring hydraulic or mechanical equipment. It can be semi-automated or fully automated, but hydraulic methods are more mature, produce better quality, are easier to control, and offer a more advanced manufacturing process. Slip casting uses plaster molds to inject zirconium oxide slurry. A binder is added during the process, and after thorough grinding and degassing, the slurry is poured into a plaster mold to obtain the finished product.
