Zirconium oxide is the main oxide of zirconium. It is usually white odorless and odorless crystal. It is an important high temperature resistant material, ceramic insulating material and ceramic sunscreen. It is also the main raw material of artificial diamond. Zirconium oxide is very common in life. It has good mechanical strength in precision ceramic products under normal temperature conditions. And it has low thermal conductivity and high toughness, and it is a product that overcomes the drawbacks of ceramics that are too brittle and fragile.
The structural design of the zirconia ceramic core is to ensure the reasonable shape of the shaft and the overall structural size, and to design a complete foundation for the zirconia ceramic shaft. Zirconium oxide is a type of part that is mounted on a ceramic shaft, fixed in size, or the main fixing tool for its position and parts. Zirconium oxide is mainly related to the properties, size and direction of the load, the type and size of the ceramic bearing, the blank of the ceramic shaft, the manufacturing and installation transportation, the assembly process, the manufacturing and the deformation of the shaft.
Zirconia ceramics have excellent properties such as high melting point and high boiling point, high hardness, insulator at normal temperature, and electrical conductivity at high temperatures. The principle of production of zirconia ceramic cores is determined by the situation. It needs to be carefully designed in advance. If necessary, a variety of production schemes should be prepared for comparison to select the best solution.
The manufacturing principles of zirconia ceramic cores are mainly as follows. First of all, we need to save materials, try to choose the cross-sectional shape with large strength or large cross-section coefficient to avoid wasting material. Secondly, we should choose a ceramic core that is easy to position, stabilize, load, disassemble and adjust the parts on the zirconia ceramic shaft to avoid the process being too complicated and difficult to assemble. We must strictly abide by the principle of making zirconia ceramic cores during the assembly process.
Then, we need to choose other structural measures to reduce the stress concentration and increase the strength, so as to avoid the stress concentration or the low strength affect the quality of the zirconia ceramic core. Finally, and most importantly, we have to choose a zirconia ceramic core that is easy to manufacture and guarantee accuracy, otherwise it will affect its quality.
