Zirkonoxidkeramiken typically require processes such as blank cutting, grinding, lapping, and polishing to produce the desired parts. Their characteristics include high-temperature firing, colorfastness, non-absorbency, non-deformation, and easy cleaning. Zirconia ceramics are suitable for use in microwave ovens, meat grinders, and other food processing applications, and are non-toxic and harmless to the human body.

Zirkonoxidkeramiken Cutting, Grinding, Lapping, and Polishing

Zirkonoxidkeramiken cutting commonly uses three methods: fixed abrasive cutting, free abrasive cutting, and single-edge cutting. High-performance zirconia ceramic application development uses ZTA (zirconia-based three-phase composite ceramic material) as raw material to develop and produce ceramic drawing dies and ceramic rollers, as well as their industrial applications. Experiments have proven that ceramic drawing dies and ceramic rollers made of ZTA material can completely replace commonly used cemented carbide drawing dies and metal rollers in industrial applications on production lines. Utilizing advanced microwave sintering technology can improve the material’s performance indicators, thereby further reducing the manufacturing cost of ceramic drawing dies and ceramic rollers.

Mechanical Properties of Zirconia Ceramics

Zirconium oxide ceramics exhibit no plastic deformation at room temperature. While possessing high compressive strength, they exhibit relatively low tensile, flexural, and impact strengths, making them prone to brittle fracture. Depending on the material composition, the theoretical strength of zirconia ceramics is very high, but its actual strength is only about 1% of the theoretical strength. This is due to variations in sintering conditions and processes, resulting in different multiphase structures. Furthermore, creep can occur when ceramics are heated to their critical temperature, and this creep is more pronounced at high temperatures. During sintering, the creep of the ceramic often pulls on the metal, leading to deformation, especially in multi-unit zirconia ceramics subjected to repeated sintering, where the possibility of deformation is even greater.

Strengthening of Zirconia Ceramics

Because zirconia ceramics exhibit brittle fracture, they cannot withstand the harsh conditions of the oral cavity. Therefore, researchers worldwide have focused on strengthening zirconia ceramics. Currently, relatively mature strengthening techniques include composite strengthening, ceramic crystallization, ceramic densification, and prestressing strengthening. The development of high-performance structural zirconia ceramic applications utilizes three-phase composite ceramic material ZTA as raw material to develop and produce ceramic drawing dies and ceramic rollers, as well as their industrial applications. Experiments have shown that ceramic drawing dies and ceramic rollers made of ZTA material can completely replace commonly used cemented carbide drawing dies and metal rollers in industrial applications on production lines. Utilizing advanced microwave sintering technology can improve the material’s performance indicators, thereby further reducing the manufacturing cost of ceramic drawing dies and ceramic rollers.
